I used a Thinkpad X61 tablet pc for note taking and lecture recording while doing my bachelors in EE, and still use it as a regular notebook and note taking now as a grad student. I recently loaded Windows 7 on a SSD and it flies. The screen's 1400x1050, so no screen real-estate complaints here. Most of the time I type my notes, but when I need to write down equations and diagrams, I flip it around and draw them, then go back to typing when I need to. It's fast enough to be a regular use noebook, especially with the new SSD. I love it. The sad thing is they don't make 12.1 inch IPS high res screens anymore, as the latest incarnation, the X200 tablet, uses a 1280x800 screen that's far inferior. Still I think it's worth a look.
