The 13.3" MacBook Air Notebook Computer from Apple is an ultraportable notebook computer with a thin and lightweight design. Apple's engineers have leveraged the lessons they learned in designing the miniaturized iPad and applied them to the design of this 2.96-pound computer. To say that the Air is svelte is all at once stating the obvious and understating the truth. The system is defined by its unibody aluminum enclosure. At its thickest point the computer is only 0.68" -- it tapers down to 0.11" at its thinnest. The system is loaded with 128GB of flash storage rather than an old-fashioned hard drive.
