I've heard good things about the Pro but the screen is just to small if I'm going to be using it as a laptop as well. I don't mind lugging around a larger screen if it means I don't need a laptop and a tablet. I'm surprised there isn't more stuff like that out there as the only 15 inch tablets aren't released yet. I'd think there's definitely a market for this. Looks like I may have to wait a little while.
edit : Actually I just found a few, still surprised there aren't many out there.
