I agree with Engadget’s take on the MacBook Air: “Give us the lovechild of the MacBook Air and the MacBook Pro, and it’s all over.”
Cool, good design, not for me (I need audio in, ethernet, optical drive, and more USB ports, so I need a different class of laptop in the first place). Eagerly awaiting the new MacBook / MacBook Pro lines rumored for launch in a few weeks.
