Loren laments that ultra-portable computers aren't Tablet PCs. Check out the Sony U-70:

Man, I'd buy a Tablet in that form-factor in a microsecond! But I've come to realize that I'm more pen-centric and more note-taking centric than most people (I have dozens of paper notebooks going back to High School, and thousands of index cards). Still, I'm not sure that I'd buy a U-70 with a touchscreen, even if the new Tablet Input Panel was available. Touchscreen's are really mushy and get scratched too easily. It's something that I've noticed between my original Palm PDAs, where writing was on a separate area (that I ended up covering with magic tape), and my PPC.
