Apple Macbook Air.

The MacBook Air is a line of laptop computers developed and manufactured by Apple Inc. It consists of a full-size keyboard, a machined aluminum case, and a thin light structure. The Air was originally positioned as a premium ultraportable positioned above the previous MacBook line. Since then, the Air has become Apple's entry-level laptop due to the original MacBook's discontinuation in 2011, as well as lowered prices on subsequent iterations. In the current product line, the MacBook Air sits below the performance range MacBook Pro.

The MacBook Air was introduced in January 2008 with a 13.3-inch screen, and was promoted as the world's thinnest notebook. Apple released a second generation MacBook Air in October 2010, with a redesigned tapered chassis, standard solid-state storage, and added a smaller 11.6-inch version. Later revisions added Intel Core i5 or i7 processors and Thunderbolt. The third generation was released in October 2018, with reduced dimensions, a Retina display, and uses combination USB-C/Thunderbolt 3 ports for data and power.
