MacBook Air is nearly as thin as your index finger. Practically every detail that could be streamlined has been. Yet it still has a 13.3-inch widescreen LED display, full-size keyboard, and large multi-touch trackpad. It’s incomparably portable without the usual ultraportable screen and keyboard compromises.
The incredible thinness of MacBook Air is the result of numerous size- and weight-shaving innovations. From a slimmer hard drive to strategically hidden I/O ports to a lower-profile battery, everything has been considered and reconsidered with thinness in mind.
MacBook Air is designed and engineered to take full advantage of the wireless world. A world in which 802.11n Wi-Fi is now so fast and so available, people are truly living untethered — buying and renting movies online, downloading software, and sharing and storing files on the web.
