I just bought a boogie board lcd tablet at the store for $30. Its pretty sweet and although it isn't extremely useful its pretty cool semi replacement for my sticky notes as if you could see my desk right now I have sticky notes all over my monitor, keyboard, desk, wall, tower, printer, everywhere lol.....

Basically you draw on it with a stylus and when you push a button it erases. Supposedly the next version will be able to save what you write and possibly even upload it to the computer.
Shit is only 1/8th an inch think... mad thin. Anyone else got one of these?
BTW: Fuck the ipad lol with the third or fourth version of this it would be better IMO.
