The MacBook Air is a line of Macintosh ultraportable notebook computers from Apple Inc. The Air was designed to balance both performance and portability, consisting of a full-sized keyboard design, a machined casing made of aluminum, and a very light and thin structure. The MacBook Air is available in two sizes, with the diagonal length of the display determining the model size: 13.3-inch and 11.6-inch (or 33.78 cm and 29.46 cm, respectively). (Usually these are regarded as 13"- resp. 11"-model.) A range of model choices with different specifications are produced by Apple, and as of 2011, all Air models use solid-state drive (SSD) storage and Intel Core i5 or i7 central processing units (CPUs).
