MacBook Air

The MacBook Air family is a line of Apple ultraportable Macintosh notebook computers.

Product history
The first-generation MacBook Air was a 13.3"-only model, previously promoted as the World's Thinnest Notebook, introduced at the Macworld Conference & Expo on January 15, 2008. It featured a custom Intel Merom CPU and 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 slightly higher-capacity battery, and a faster Penryn CPU.

On October 20, 2010, Apple released a redesigned 13.3" model, with improved enclosure, screen resolution, battery, and flash storage instead of a hard drive. In addition, a new 11.6" model was introduced, offering reduced cost, weight, battery life, and performance relative to the 13.3" model, but better performance than typical netbooks of the time.

On July 20, 2011, Apple released an updated model in the same form factor as the prior model. The new model was powered by new dual-core Intel Core i5 and i7 processors, had a backlit keyboard, Thunderbolt instead of Mini DisplayPort and Bluetooth was upgraded to v4.0. Maximum flash storage and memory options were almost identical.
