The MacBook Air family is a line of Apple ultraportable Macintosh notebook computers.
The first MacBook Air was a 13.3" model, 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 faster non-custom Penryn CPU and Nvidia GeForce graphics while the hard drive capacity increased and the micro-DVI video port replaced by a 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 uses 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.
On July 20, 2011, Apple released an updated model in the same form factor as the previous model. The backlit keyboard was re-added, Mini DisplayPort was made into a Thunderbolt port, powered by new dual-core Intel Core i5 and i7 processors and the Bluetooth was upgraded to v4.0. Maximum flash storage and memory options were almost identical.
