Apple Mac Book Air MD711 11inch 1.3Ghz 128GB SSD i5 Silver

Apple's engineers have leveraged the lessons they learned in designing the miniaturized iPad and applied them to the design of this 2.38-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. Flash storage doesn't just give you a lighter, thinner computer. It also allows for impressive battery life -- up to 9 hours of web browsing and 30 days of standby time.
