I recently bought the AIPTEK 12.1" Slim tablet and it works very well. I am able to Ink wherever it is supported: Word 2007, OneNote, Journal, StickyNotes, and some other places. OneNote is a very handy place to do my Ink stuff. I did compare it to the Wacom offerings and decided this was a better value; the AIPTEK had about 1/2 the cost per square inch of writing surface. I also like its 'slimness' as it fits well in the pull out tray of my working desk. One negative is that the AIPTEK program that monitors the HotKeys along the top and sides accesses the hard drive once per second and I did not like the constant activity; so I have their MacroKey Manager turned off until I really need the HotKeys.
As I recall, the Wacom Bamboo comes with a mouse which I decided would be more problem than help. I organize my work area so that when I need a mouse function, I use my regular mouse.
I am having a lot of fun learning to sketch on/with the tablet.
