The 13.3 MacBook Air Notebook Computer from Apple is an ultra portable 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 2.38-pound computer. To say that the Air is svelte is all at once stating the obvious and understating the truth. The system is loaded with 64GB 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.
