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. A mid-2009 refresh, introduced alongside the MacBook Pro family, featured a slightly higher-capacity battery, and a faster Penryn CPU. 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. It featured a custom Intel Merom CPU and Intel GMA graphics. 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. The MacBook Air family is a line of ultraportable Macintosh notebook computers created by Apple Inc.
