Apple Wireless Keyboard
The Apple Wireless Keyboard is a wireless keyboard built for Macintosh computers and compatible with iOS devices. It interacts over Bluetooth wireless technology and unlike its wired version, it has no USB connectors or ports. Both generations have low-power features when not in use, it was discontinued on October 13, 2015, was succeeded by the new Magic Keyboard. The first generation Apple Wireless Keyboard was released at the Apple Expo on September 16, 2003, it was based on the updated wired Apple Keyboard, featured white plastic keys housed in a clear plastic shell. Unlike the wired keyboard, there are no USB ports to connect external devices; the bottom of the keyboard has an on/off switch. The device is not compatible with iPhone and iPad devices, it is only compatible with Macintosh computers running Mac OS X 10.2.6 or later. On August 7, 2007, Apple released a redesigned model of the Apple Wireless Keyboard. Like the wired Apple Keyboard, the new model is thinner than its predecessors and has an aluminum enclosure.
Another addition is the new functions added to the function keys, such as media controls and Dashboard control. Unlike the previous version, the Wireless Keyboard now has a layout similar to the MacBook; the power button has been relocated to the right side of the keyboard, the layout does not include a numeric keypad. This model added accidental caps lock prevention: the key has to be held down for a moment for caps lock to engage; this keyboard required one fewer than its predecessor. In October 2009, a revised third model was released. New model number A1314 replaced two years and two months after the initial release; the new model now uses only two AA batteries instead of three originally. Additionally, Mac OS X 10.5.8 is now the minimum OS over the original Mac OS X 10.4.10. This model of keyboard became standard with new generation of iMacs introduced on the same day. On July 20, 2011, following the release of Mac OS X 10.7/OS X Lion, Apple updated the keyboard updating the label on the Exposé key to Mission Control and changing the Dashboard key to a Launchpad key.
Keyboard layouts with a rectangular Enter key are Korean. Keyboard layouts with L-shaped Enter keys are available in: Due to the missing keys for Windows PCs, Apple has made mappings. Note; these keyboard mappings will work on a Mac operating under Windows 7 when running Boot Camp, but may not work if the user selects the Boot Camp option of "Use all F1, F2, etc. keys as standard function keys" Although Apple includes support for Macintosh computers, it can be used on a Microsoft Windows PC providing that a Bluetooth receiver and appropriate Bluetooth stack is installed and properly configured. The Linux kernel supports Apple Wireless Keyboards via the hid-apple module, present in 2.6.x+ kernels.

IMac is a family of all-in-one Macintosh desktop computers designed and built by Apple Inc. It has been the primary part of Apple's consumer desktop offerings since its debut in August 1998, has evolved through seven distinct forms. In its original form, iMac G3 had a gumdrop or egg-shaped look, with a CRT monitor enclosed by a colored, translucent plastic case, refreshed early on with a sleeker design notable for its slot-loaded optical drive; the second major revision, iMac G4, moved the design to a hemispherical base containing all the main components and an LCD monitor on a moving arm attached to it. The third and fourth major revisions, iMac G5 and the Intel iMac placed all the components behind the display, creating a slim unified design that tilts only up and down on a simple metal base; the fifth major revision shared the same form as the previous model, but was thinner and used anodized aluminum and a glass panel over the entire front. The sixth major revision uses a different display unit, omits the SuperDrive, uses different production techniques from the older unibody versions.
This allows it to be thinner with an edge thickness of 5.9 mm. It includes a dual microphone setup, includes solid-state drive or hard disk storage, or an Apple Fusion Drive, a hybrid of solid state and hard disk drives; this version of iMac was announced in October 2012, with the 21.5-inch version released in November and the 27-inch version in December. In October 2014, the seventh major revision of the 27-inch iMac was announced, whose main feature is a "Retina 5K" display at a resolution of 5120 × 2880 pixels; the new model includes a new processor, graphics chip, IO, along with several new storage options. The seventh major revision of the 21.5-inch iMac was announced in October 2015. Its main feature is a "Retina 4K" display at a resolution of 4096 × 2304 pixels, it has the same new processor, graphics chip, I/O as the 27-inch iMac, along with several new storage options. On June 5, 2017, Apple announced a workstation-class version of the iMac, called the "iMac Pro"; the iMac Pro shares the design and screen of the 5K iMac, but is colored in Space Gray rather than silver.
It comes with standard SSD storage. Apple began shipping the iMac Pro in December 2017; the announcement of iMac in 1998 was a source of controversy and anticipation among commentators, Mac fans, detractors. Opinions were divided over Apple's drastic changes to the Macintosh hardware. At the time, Apple had suffered a series of setbacks as consumers opted for Wintel machines instead of Apple's Performa models. Many in the industry thought that "beleaguered" Apple would soon be forced to start selling computers with a custom interface built on top of one or more potential operating system bases, such as Taligent, Solaris, or Windows 98. Part of Apple's effort to maintain the Mac platform was trying to improve its retail strategy; as these stores developed, they became a detriment to Apple sales, as CompUSA employees were unfamiliar with the Macintosh and directed customers to Wintel boxes instead. The designer behind iMac's case was Jonathan Ive. Ken Segall was an employee at an L. A. ad agency handling Apple's account who came up with the name "iMac" and pitched it to Steve Jobs.
Jobs wanted the product to be called "MacMan", but warmed to Segall's suggestion. Segall says that the "i" stands for "Internet", but represents the product as a personal and revolutionary device. Apple adopted the'i' prefix across its consumer hardware and software lines, such as iPod, iBook, iPhone, iPad and various pieces of software such as the iLife suite and iWork and the company's media player/store, iTunes. Attention was given to the out-of-box experience: the user needed to go through only two steps to set up and connect to the Internet. "There's no step 3!" was the catch-phrase in a popular iMac commercial narrated by actor Jeff Goldblum. Another commercial, dubbed "Simplicity Shootout", pitted seven-year-old Johann Thomas and his border collie Brodie, with an iMac, against Adam Taggart, a Stanford University MBA student, with an HP Pavilion 8250, in a race to set up their computers. Johann and Brodie finished in 8 minutes and 15 seconds, whereas Adam was still working on it by the end of the commercial.
By 2005, it had become more and more apparent that IBM's development for the desktop implementation of PowerPC was grinding to a halt. Apple announced at the Worldwide Developers Conference that it would be switching the Macintosh to the x86 architecture and Intel's line of Core processors; the first Intel-equipped Macs were unveiled on January 10, 2006: the Intel iMac and the introductory MacBook Pro. Within nine months, Apple had smoothly transitioned the entire Macintosh line to Intel. One of the touted side benefits of this switch was the ability to run Windows on Mac hardware. On July 27, 2010, Apple updated its line of iMacs to feature the new Intel Core "i-series" processors across the line; the 21.5" models now feature the Core i3 processor, but these are upgradable to the Core i5. The high end 27" features a Quad-Core i5 processor, upgradable to a Quad-Core i7. On this date Apple announced its new "Apple Magic Trackpad" peripheral, a trackpad similar to that of MacBook Pro for use with iMac or any other Apple computer.
The MacBook Air is a line of laptop computers developed and manufactured by Apple Inc. It consists of a full-size keyboard, a machined aluminum case, a thin light structure; the Air is available with a screen size of 13.3-inch, with different specifications produced by Apple. Since 2010, all MacBook Air models have used solid-state drive storage and Intel Core i7 CPUs. A MacBook Air with an 11.6-inch screen was made available in 2010 through late 2016. In the current product line, the MacBook Air sits below the performance-range of the MacBook Pro and compared to the MacBook, its features reflect different priorities; the Air was released as a premium ultraportable positioned above the previous MacBook. Since the Air has become Apple's entry-level laptop due to the MacBook's discontinuation in 2011, as well as lowered prices on subsequent iterations. Steve Jobs introduced the first MacBook Air during a speech at his keynote at the 2008 Macworld conference held on January 15, 2008; the first-generation MacBook Air was a 13.3"-only model promoted as the world's thinnest notebook.
It featured a custom Intel Merom Intel GMA graphics. In late 2008, the CPU was updated to a faster, non-custom Penryn CPU and integrated Nvidia GeForce graphics while the hard drive capacity was increased and the micro-DVI video port was replaced by the Mini DisplayPort. A mid-2009 refresh, introduced alongside the MacBook Pro family, featured a higher-capacity battery, a faster Penryn CPU; the MacBook Air features an anti-glare LED backlit display and a full-size keyboard, as well as a large trackpad that responds to multi-touch gestures such as pinching and rotating. Since the release of Snow Leopard, the Air's trackpad has supported handwriting recognition of Chinese characters; the MacBook Air was the first subcompact laptop offered by Apple since the full-featured 12" PowerBook G4 was discontinued in 2006. It was Apple's first computer with an optional solid-state drive. ArsTechnica found "moderate" performance improvements of the 64 GB solid-state drive of the first-generation Air over the standard 80 GB hard drive in tests.
On October 14, 2008, new models were announced with improved capacities of 128 GB SSD and 120 GB hard drive. The CPU was a custom Intel Core 2 Duo Merom, 40% of the size of the standard chip package. For models of late 2008, the CPU was replaced with a low-voltage Penryn chip with 6MB of cache, running on a 1066 MHz bus. Following its introduction, the MacBook Air received a mixed reception. Reviews criticized the compromises made in terms of features; the full-sized keyboard, weight and Multi-Touch trackpad were appreciated in reviews, while the limited configuration options and ports, slow speed, non-user-replaceable battery, small hard drive, price were criticized. The flip-down hatch on the side of the original MacBook Air is a tight fit for some headphone plugs and USB devices, requiring users to purchase an extension cable. Apple removed the flip-down hatch on the late 2010 model in favor of open connection ports, as is the case with most other laptops; some users have complained of CPU lockup caused by overheating.
Apple released a software update in early March 2008 to fix the problem with mixed results: the deactivation of one CPU core was corrected. The problem is aggravated by system-intensive tasks such as video video chatting. At the launch of the MacBook Air in January 2008, Apple claimed it to be the thinnest laptop in the world. While this was true of laptops on sale at the time, the 2003 Sharp Actius MM10 Muramasas was thinner at some points than the MacBook Air, being 0.54 inches thick at its minimum. It, like the MacBook Air, was a tapered design, with a maximum height of 0.78 inches —slightly thicker than the MacBook Air — shown above as 0.76 inches. The Sony Vaio X505, released in 2004, had a minimum thickness of 0.38 inches and a maximum of 0.8 inches. Since the release of the MacBook Air, other thinner laptops have been released, such as the Dell Adamo, launched in March 2009, a constant 0.65 inches thick. Apple subsequently removed the claim of being "the world's thinnest notebook" from their marketing materials.
On October 20, 2010, Apple released a redesigned 13.3-inch model with a tapered enclosure, higher screen resolution, improved battery, flash storage instead of a hard drive. In addition, a new 11.6-inch model was introduced, offering reduced cost, battery life, performance relative to the 13.3-inch model, but better performance than typical netbooks of the time. On July 20, 2011, Apple released updates to the 11.6-inch and 13.3-inch models of the MacBook Air, which became Apple's entry-level laptops due to lowered prices and the discontinuation of the white MacBook around the same time. The mid-2011 MacBook Airs were powered by the new Sandy Bridge 1.6 or 1.7 GHz dual-core Intel Core i5, or 1.8 GHz dual-core Intel Core i7 processors, that came with an Intel HD Graphics 3000 processor, with a backlit keyboard, two USB 2.0 ports, FaceTime camera, a standard of 2 GB of RAM, Thunderbolt which shares function with Mini DisplayPort and Bluetooth was upgraded to v4.0. Maximum SSD flash memory storage options were increased up to 256 GB.
Both 11-inch and 13-inch models had an analog audio output/headphone minijack, but only the 13-inch model had an integrated SDXC-capable SD Card slot. These models use a less expensive "Eagle Ridge"
A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface; the first public demonstration of a mouse controlling a computer system was in 1968. Wired to a computer, many modern mice are cordless, relying on short-range radio communication with the connected system. Mice used a ball rolling on a surface to detect motion, but modern mice have optical sensors that have no moving parts. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as selection of a menu item on a display. Mice also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input; the earliest known publication of the term mouse as referring to a computer pointing device is in Bill English's July 1965 publication, "Computer-Aided Display Control" originating from its resemblance to the shape and size of a mouse, a rodent, with the cord resembling its tail.
The plural for the small rodent is always "mice" in modern usage. The plural of a computer mouse is "mouses" and "mice" according to most dictionaries, with "mice" being more common; the first recorded plural usage is "mice". The term computer mouses may be used informally in some cases. Although, the plural of mouse is mice, the two words have undergone a differentiation through usage; the trackball, a related pointing device, was invented in 1946 by Ralph Benjamin as part of a post-World War II-era fire-control radar plotting system called Comprehensive Display System. Benjamin was working for the British Royal Navy Scientific Service. Benjamin's project used analog computers to calculate the future position of target aircraft based on several initial input points provided by a user with a joystick. Benjamin felt that a more elegant input device was needed and invented what they called a "roller ball" for this purpose; the device was patented in 1947, but only a prototype using a metal ball rolling on two rubber-coated wheels was built, the device was kept as a military secret.
Another early trackball was built by British electrical engineer Kenyon Taylor in collaboration with Tom Cranston and Fred Longstaff. Taylor was part of the original Ferranti Canada, working on the Royal Canadian Navy's DATAR system in 1952. DATAR was similar in concept to Benjamin's display; the trackball used four disks to pick up two each for the X and Y directions. Several rollers provided mechanical support; when the ball was rolled, the pickup discs spun and contacts on their outer rim made periodic contact with wires, producing pulses of output with each movement of the ball. By counting the pulses, the physical movement of the ball could be determined. A digital computer calculated the tracks and sent the resulting data to other ships in a task force using pulse-code modulation radio signals; this trackball used a standard Canadian five-pin bowling ball. It was not patented. Douglas Engelbart of the Stanford Research Institute has been credited in published books by Thierry Bardini, Paul Ceruzzi, Howard Rheingold, several others as the inventor of the computer mouse.
Engelbart was recognized as such in various obituary titles after his death in July 2013. By 1963, Engelbart had established a research lab at SRI, the Augmentation Research Center, to pursue his objective of developing both hardware and software computer technology to "augment" human intelligence; that November, while attending a conference on computer graphics in Reno, Engelbart began to ponder how to adapt the underlying principles of the planimeter to X-Y coordinate input. On November 14, 1963, he first recorded his thoughts in his personal notebook about something he called a "bug," which in a "3-point" form could have a "drop point and 2 orthogonal wheels." He wrote that the "bug" would be "easier" and "more natural" to use, unlike a stylus, it would stay still when let go, which meant it would be "much better for coordination with the keyboard."In 1964, Bill English joined ARC, where he helped Engelbart build the first mouse prototype. They christened the device the mouse as early models had a cord attached to the rear part of the device which looked like a tail, in turn resembled the common mouse.
As noted above, this "mouse" was first mentioned in print in a July 1965 report, on which English was the lead author. On 9 December 1968, Engelbart publicly demonstrated the mouse at what would come to be known as The Mother of All Demos. Engelbart never received any royalties for it, as his employer SRI held the patent, which expired before the mouse became used in personal computers. In any event, the invention of the mouse was just a small part of Engelbart's much larger project of augmenting human intellect. Several other experimental pointing-devices developed for Engelbart's oN-Line System exploited different body movements – for example, head-mounted devices attached to the chin or nose – but the mouse won out because of its speed and convenience; the first mouse, a bulky device used two potentiometers perpendicular to each other and connected to wheels: the rotation of each wheel translated into motion along one axis. At the time of the "Mother of All Demos", Engelbart's group had been using their second generation, 3-button mouse for about a year.
On October 2, 1968, a mouse device named Rollkugel (German for "rolling bal
The PowerBook G3 is a series of laptop Macintosh personal computers designed and sold by Apple Computer, Inc. from 1997 to 2001. It was the first laptop to use the PowerPC G3 series of microprocessors, was marketed as the fastest laptop in the world for its entire production run; the PowerBook G3 was succeeded by the PowerBook G4. The first Macintosh PowerBook G3, code-named "Kanga," was introduced in November 1997. At the time of its introduction, the PowerBook G3 was advertised as the fastest notebook computer available; this model was based on the PowerBook 3400c, was unofficially known as the PowerBook 3500. It used the same case as the 3400c, a similar motherboard; the motherboard was upclocked from 40 MHz to 50 MHz, resulting in some incompatibility with older 3400 RAM modules. Other changes to the motherboard included doubling the on-board RAM from 16 MB to 32 MB, a faster version of the on-board Chips and Technologies graphics controller; the G3 made the Kanga more than twice as fast as a 3400c, the improved graphics controller allowed it to refresh the screen 74 percent faster.
This first PowerBook G3 shipped with a 250 MHz G3 processor and a 12.1" TFT SVGA LCD. It is the only G3 system, not compatible with Mac OS X; the Kanga was on the market for less than 5 months, is regarded as a stopgap system that allowed Apple to ship G3 PowerBooks sooner, while Apple prepared its more revolutionary PowerBook G3 Series. As a result, the Kanga has the dubious distinction of being Apple's fastest depreciating PowerBook. Many people chose to purchase a Kanga to continue using their interchangeable expansion bay modules and other peripherals from the Powerbook 190, 5300 and 3400 models; the Kanga was notably smaller in depth and width than the subsequent Wallstreet Powerbooks, the Kanga remained the smallest-when-open G3 laptop until the debut of the Apple iBook some years later. The second generation of PowerBook G3s, now called the PowerBook G3 Series, was introduced in March 1998; the machine was redesigned with a new case, lighter and more rounded than the previous PowerBook G3.
The new PowerBooks, code-named Wallstreet, came in three screen sizes: a 12" passive matrix LCD, a 13.3" TFT LCD, a 14.1" TFT LCD. It came in three CPU speeds: 233 MHz, 250 MHz, 292 MHz; the 233 MHz model was sometimes nicknamed Mainstreet, as it lacked L2 cache, making it far slower than the other two in the lineup. The 250 MHz and 292 MHz models shipped with 1 MB of cache; because of this large cache, as well as the swifter system bus, the Wallstreets were known to suffer from some heat issues. Many of the problems of the Wallstreet PowerBook G3s were fixed in the next revision, the Wallstreet II; the Wallstreet design was updated in August 1998. It featured a 14.1" display on all models. Processor speeds were bumped on the faster two models, resulting in 233 MHz, 266 MHz, 300 MHz models; the case contained one on each side. The left-hand bay could accommodate a battery, a 3.5" floppy disk, a third-party Iomega Zip drive, or a third-party add-on hard drive. The right-hand bay could accommodate any of the above plus a 5-1/4" optical drive.
A small internal nickel-cadmium battery allowed swapping of the main batteries while the computer "slept." With a battery in each bay, battery life was doubled. DVDs could be displayed with the use of a hardware decoder built into a CardBus card; the PowerBook G3 Series was Apple's first notebook offering that matched the build-to-order customization of the Power Mac G3 desktop line. Discontinued in May 1999, this would be the last Apple computer to bear the rainbow-colored Apple logo and the last Mac to support Apple's Superdrive, it was the last Old World ROM model in the PowerBook series. The third generation of PowerBook G3 was introduced in May 1999, it was the first New World ROM PowerBook. It had longer battery life, as with the Wallstreet II the user could double the duration to 10 hours by substituting a second battery for the optical drive in the expansion bay; the keyboard was improved and now featured translucent bronze-tinted plastics, the origin of the "bronze keyboard" nickname. The Lombard was the second PowerBook to use industry-standard ATA optical drives.
This change meant that CD and DVD recorders designed for wintel machines could more be used in this computer at a price far less than those manufactured by Apple. Internal hard drives for the Pismo and Wallstreet II can be used interchangeably; the expansion bay drives are interchangeable on the Lombard, but not on the Wallstreet. A DVD drive was optional on the 333 MHz standard on the 400 MHz version; the 400 MHz model included a hardware MPEG-2 decoder for DVD playback, while the 333 MHz model was left without. Further DVD playback optimizations enabled both models to play back DVDs without use of hardware assistance; this model introduced USB ports to the PowerBook line while retaining SCSI support and eliminating ADB entirely. Graphics were provided by a Rage LT Pro chipset on the PCI bus, to drive its 14.1-inch LCD at a maximum resolution of 1024×768. Mac OS 8.6–10.3.9 are supported by Apple, but 10.4 is not, although OS X will not install (except fo
The MacBook was a line of Macintosh notebook computers designed and sold by Apple Inc. from May 2006 to February 2012. A new line of computers by the same name was released in 2015, serving the same purpose as an entry-level laptop, it replaced the iBook series and 12-inch PowerBook series of notebooks as a part of Apple's transition from PowerPC to Intel processors. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro, the MacBook was aimed at the consumer and education markets, it was the best-selling Macintosh ever. For five months in 2008, it was the best-selling laptop of any brand in US retail stores. Collectively, the MacBook brand is the "world's top-selling line of premium laptops."There have been four separate designs of the MacBook. The original model used a combination of polycarbonate and fiberglass casing, modeled after the iBook G4; the second type was introduced in October 2008 alongside the 15-inch MacBook Pro.
A third design, introduced in late 2009, had a polycarbonate unibody casing. On July 20, 2011, the MacBook was discontinued for consumer purchase as it had been superseded by the MacBook Air which had a lower entry price. Apple continued to sell the MacBook to educational institutions until February 2012; the original MacBook, available in black or white colors, was released on June 28, 2006, used the Intel Core Duo processor and 945GM chipset, with Intel's GMA 950 integrated graphics on a 667 MHz front side bus. Revisions of the MacBook moved to the Core 2 Duo processor and the GM965 chipset, with Intel's GMA X3100 integrated graphics on an 800 MHz system bus. Sales of the black polycarbonate MacBook ceased in October 2008, after the introduction of the aluminum MacBook. While thinner than its predecessor – the iBook G4 – the MacBook is wider than the 12-inch model due to its widescreen display. In addition, the MacBook was one of the first to adopt Apple's MagSafe power connector and it replaced the iBook's mini-VGA display port with a mini-DVI display port.
The iBook's discrete graphics chip was replaced by an integrated Intel GMA solution, though the latest revisions of the MacBook were upgraded with the more powerful Nvidia GeForce 9400M and the 320M. While the MacBook Pro followed the industrial design standard set by the PowerBook G4, the MacBook was Apple's first notebook to use features now standard in its notebooks – the glossy display, the sunken keyboard design and the non-mechanical magnetic latch. With the late 2007 revision, the keyboard received several changes to mirror the one which shipped with the iMac, by adding the same keyboard short-cut to control multimedia, removing the embedded numeric keypad and the Apple logo from the command keys. A more expensive black model was offered until the introduction of the unibody aluminum MacBook; the polycarbonate MacBook was the only Macintosh notebook to be offered in more than one color since the iBook G3. The ports are all on the left edge. For the unibody polycarbonate MacBook, the ports from left to right are the MagSafe power connector, Gigabit Ethernet, Mini DisplayPort, 2 USB 2.0 ports, audio out and Kensington Security Slot.
On the front, there is a power light and an infrared receiver, while on the right edge, there is only the optical drive. The polycarbonate Intel MacBook is easier for users to upgrade than its predecessor. Where the iBook required substantial disassembly to access internal components such as the hard drive, users only need to remove the battery and the RAM door to replace the MacBook drive. Apple provides do-it-yourself manuals for these tasks. In February 2007, the MacBook was recalled because the graphics card and hard drive caused the computer to overheat, forcing the unit to shut down; some early polycarbonate MacBook models suffered from random shutdowns. There were cases reported of discolored or chipping palmrests. In such cases, Apple asked affected owners to contact AppleCare. There were problems with batteries on some models from 2007 not being read by the MacBook; this is caused by a logic board fault and not a fault with the battery. In February 2010, Apple announced a recall for MacBooks bought between 2006–2007 for hard drive issues.
This is caused by heat and other problems. Apple used the A1181 code, printed on the case, for this family of models, though 17 variations may be counted if color is included. Notes:1 Requires the purchase of a wireless-N enabler software from Apple in order to enable the functionality. Enabled in Mac OS X 10.6 and later. 2 Hard drives noted. As the hard drive is a user-replaceable part, there are custom configurations available, including use of 7200-rpm drives or SSDs.3 Given optical drive speed is its maximum. 4 Beginning with the early 2008 revision, the Apple Remote became an optional add-on.5 Expandable to 4 GB, with 3.3 GB usable.6 Expandable to 8 GB, but with only 6 GB working stably with a Mac OS X older than 10.6.6 due to a software bug. For the pro laptop resembling it, see: MacBook Pro On October 14, 2008, Apple announced a MacBook featuring a new Nvidia chipset at a Cupertino, California press conference with the tagline: "The spotlight turns to notebooks"; this MacBook replaced the black models of the polycarbonate generation.
The chipset brought a 1066 MHz system bus, use of DDR3 system memory, integrated
The iPad 2 is a tablet designed and marketed by Apple Inc. Compared to the first iPad, as the second model in the iPad line it gained a faster dual core A5 processor, a lighter build structure, was the first iPad to feature VGA front-facing and 720p rear-facing cameras designed for FaceTime video calling; the device was available with three storage sizes—16, 32, 64GB—and two varying connectivity options—Wi-Fi only or Wi-Fi and cellular. Each variation of the device is available with either a white front glass panel. However, upon the release of the 3rd generation iPad in March 2012, only the 16GB variation with two connectivity options and two front color options remained available; the product became available in March through May 2011. The device received mixed to positive reception from various publications. Although it was praised for its hardware improvement, such as the new Apple A5 chip, the software restriction on the iPad 2 and iOS in general drew criticism from various technology commentators.
The device sold well in its first month of sales with 2.4–2.6 million units sold and 11.12 million units were sold in the third quarter of 2011. A popular product, with a lower screen resolution and performance than the two Retina models that followed it but a lighter build and longer battery life, it remained in the Apple line-up as an entry-level iPad model for three years until March 2014, latterly with a silent upgrade to a die-shrunk version of the A5 processor, its basic design formed the core of the first iPad mini, which had the same screen pixel count and similar features at a smaller size. The iPad 2 was the only device to receive six major versions of iOS, from 4 to 9. Apple sent invitations to journalists on February 23, 2011, for a media event on March 2. On March 2, 2011, CEO Steve Jobs unveiled the device at the Yerba Buena Center for the Arts, despite being on medical leave. Upon the announcement of the iPad 2, the original iPad was discontinued from sales online and at Apple authorized retail stores.
Apple began selling the iPad 2 on its website on March 11, in its U. S. retail stores at 5 pm local time on that date. Many stores in major cities, such as New York, sold out within hours. Online shipping delays had increased to three to four weeks on Sunday and four to five weeks by Tuesday; the iPad 2 was released internationally in 25 other countries on March 25, 2011. The countries included Australia, Belgium, Czech Republic, Finland, Germany, Iceland, Ireland, Luxembourg, Netherlands, New Zealand, Poland, Spain, Sweden and the United Kingdom; the April 29, 2011 release date for Japan was postponed due to the earthquake and tsunami which struck the nation on March 11, 2011. The iPads were delayed due to the NAND flash storage chip used in the iPads being created by Toshiba, affected by the earthquake and tsunami thus resulting in the suspension of operations for an indefinite period of time; the slowdown caused analysts to downgrade Apple's stock. The iPad 2 was released in Hong Kong, South Korea, Philippines and other countries including Japan on April 29, 2011.
It was released in numerous other nations which include China, Thailand, Brazil and Taiwan on two major release dates, May 6 and 27.
