As we all know (and rumored before), Apple announced a new line of portable computers during Steve Jobs' keynote speech at Macworld 2008 held at San Francisco's Moscone Center recently, the MacBook Air.

The new machines feature a multi-touch trackpad, allowing the user to double-tap and move. Rotate a photo by pivoting your index finger around your thumb, as well as pinch & zoom. This new product is a complement to the existing MacBook and MacBook Pro lines.
