ZenBook is a family of ultrabooks – low-bulk laptop computers – produced by Asus. The first ZenBooks were released in October 2011, and the original range of products was amended and expanded during 2012. Models range from 12-inch laptops featuring power efficient components but lacking connectivity and having only integrated graphics processors, to 15-inch laptops with discrete graphics processing units and optical disc drives. Most ZenBooks use Intel Core ultra-low-voltage processors and Nvidia GPUs when integrated graphics are not used. Asus introduced new models with touch screens to take advantage of Windows 8 after its release in late 2012. Most models drew comparisons to the MacBook Air. The ZenBook mainly competes against computers such as Acer's Aspire, Dell's Inspiron and XPS, HP's Pavilion, HP Stream and Envy, Lenovo's IdeaPad, Samsung's Sens and Toshiba's Satellite.
