Surface Pro is on my radar. I've had my Tablet PC since January 2006 and it's served me VERY well...through XP Tablet Edition, Vista, and now Windows 7.

If I get a Surface Pro, put on Office(including the very necessary OneNote), and a few other programs...I'm set.

It's bonus for sure is the digitizer. It's a laptop on your desk, snap off the keyboard to go to a meeting, now it's a tablet PC with pen input. WIN!
