personally i dont like those tablets, but you should really check out some Wacom stuff
http://www.wacom.com/cintiq/cintiq-21ux.php this is really cool its like an actual censor screen with pressure levels that you can draw on. reallly cool stuff. i wanna get one but they are really hard to get in russia and they cost about 2000 bucks (for the 21 inch) this is much better than just a regular tablet pc panel as it recognises 2000 levels of pressure, the screen is durable, and its just in every wy better than a tablet PC
dont hate people who rip you off,cheat and get away with it, learn from them
