I hear the ThinkPad X61 Tablet is pretty good...although I like all ThinkPads anyway. I have a 4 year old Acer TravelMate C110. This thing's build quality is crap, but it is pretty rugged IMO, but its EXTREMELY slow at a clock speed of 1Ghz and only 508MB RAM. This is with WinXP Pro Tablet PC Edition, which is known to be the most buggy one in a long time. Anyway, back on topic. I also hear good things about the Dell Latitude XT but its really pricey and generally I don't like Dell's.
