The MacBook Unibody is a hybrid of the original MacBook and the MacBook Air, packing all the features of the MacBook into a more stylish and lighter weight aluminum enclosure. To create an incredibly thin and light machine, Apple made a number of compromises, including omitting the optical drive, using a 1.8' hard drive (normal is 2.5'), and integrating the RAM into the logic board, preventing future RAM upgrades.Īfter more than two years and numerous incremental upgrades, Apple announced a completely new MacBook model in October 2008, the MacBook Unibody. The MacBook Air, touted as the world's thinnest notebook, featured an aluminum enclosure. The standard MacBook model came in a white plastic enclosure, while the high-end model was also offered with a black enclosure.Ī completely new design was added to the family in January 2008 with the release of the three pound MacBook Air.
