Not a fully functioning Tablet PC, but this is a really cool ‘ink’ device. Take a look at the Aiptek My Note Digital Notepad. Write up to 135 pages of notes (you can expand this via SD card) on this ‘clipboard’. Most interesting to me is that you can take notes for up to 20 hours on 5 AAA batteries! Sync up this Notepad when you get done to your Tablet PC and you have a really interesting companion device to take to those long meetings, days at school… wherever you can think.
