「MacBook Air」was introduced on January 14th. At 3 pounds, it's right there with some of the lightest notebooks and 2 pounds less than the current MacBook, though still heavier than the 2-pound Eee PC from Asus. The MacBook Air feels like a big blade in your hand.
The MacBook Air will be 0.16 inches thick. The thickness part of the MacBook Air is still thinner than the Sony thin and lights, and will fit into an interoffice letter envelope. It will have a full-size keyboard and display, at 13.3 inches widescreen.
The display is LED backlit, which saves power and is instant -on and bright. There’s an ambient light sensor on the keyboard to make it backlit.
