The 11.6" MacBook Air Notebook Computer from Apple is an extremely portable, stunningly designed laptop computer. Apple's engineers have leveraged the lessons they learned in designing the miniaturized iPad and applied them to the design of this 2.4 -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 sleek lines and stunning aluminum enclosure. At its thickest point, the computer is only 0.68" -- it tapers down to 0.11" at its thinnest.
