I dunno I got robbed out of going to Macworld this year, but I was really hoping for a 12" macbook. I'm still rocking my 12" powerbook, too. It's still fast enough to where it doesn't bother me, or hinder my work or anything.
The MacbookAir just isn't the ultra portable I'm looking for heh. I'll probably just end up with a Macbook once the powerbook takes a crap.
