Apple MacBook Air

Apple announced the new MacBook Air as the world's thinnest laptop at MacWorld in San Francisco on January 15th, 2008. Its thickness varies from 0.16" to 0.76" as measured from different points along its edge and weighs about 3 lbs. It features a 13.3" LED backlit display, a full-size backlit keyboard, and an oversized multi-touch trackpad. Apple has made use of several new technologies and design features to create an ultra-thin form factor laptop. It does not include an optical media drive.
