MacBook Air is carved from a solid sheet of aluminum. This revolutionary unibody design replaces many parts with just one and results in a clean, seamless appearance. The anodized aluminum surface and stunning contours confirm MacBook Air as a feat of beautiful engineering. The thinness of MacBook Air is stirring. But even more impressive, there’s a full-size, fully capable notebook encased in the 0.16 to 0.76 inch of sleek, sturdy anodized aluminum. And at just 3.0 pounds,* MacBook Air is more than portable. It’s with you everywhere you go. The keyboard is full size, and its backlit keys make it easy to work in the dim lighting of airplanes and conference halls. A built-in ambient light sensor automatically adjusts keyboard illumination and display brightness for optimal visibility. And with the spacious trackpad and support for Multi-Touch technology, you can get a lot done with a simple gesture or two.The moment you open MacBook Air, you’re greeted by instant full screen brightness. Its slim design doesn’t compromise on size: The glossy 13.3-inch, widescreen LED-backlit MacBook Air display offers the same viewable size as the screen on the new 13-inch MacBook Pro. The 1280-by-800 resolution gives you vibrant images and rich colours, making it perfect for watching your own in-flight movies. And LED technology makes the display more power efficient, which translates into longer battery life.
