The MacBook Air family is a line of ultraportable Macintosh notebook computers created by Apple Inc. They were designed to balance performance and portability; therefore, they have a full-sized laptop keyboard design and, at the same time, a machined aluminium casing with extremely low weight and thickness. The MacBook Air is available in two sizes: 11.6 inch and 13.3 inch (or 29.46 cm and 33.78 cm, respectively). The measurement refers to the diagonal display size. There is a range of model choices with different specifications, however all models currently use SSD storage and Intel Core i5 and i7 CPUs. In Apple's product line, the MacBook Air occupies a position between the tablet computer iPad and iPod touch running iOS and the thicker and higher-performance MacBook Pro laptops. The MacBook Air inspired a competing range of Ultrabook computers produced by other manufacturers.Steve Jobs introduced the first MacBook Air during a speech at his keynote at the 2008 Macworld Conference & Expo on January 15, 2008. The first-generation MacBook Air was a 13.3"-only model, initially promoted as the world's thinnest notebook. 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.
