Well, I suggested that the MacBook Air might be a tablet style computer. I was wrong. It was just a really, really slim lightweight version of the current line. The features set sounds like a hybrid of the MacBook and MacBook Pro lines. You can check out one early description here.
I'd be interested in what you think. Is this something that has you wanting to run out and drop over two grand (w/ tax & Applecare)? I'd especially be interested in the opinion of geekbert's unofficial correspondent on the ground at MacWorld, JayDog. What's it like up close and personal?
