The doodle-and-text "game" for the DS was playable, and was a great tool for getting a feel for the DS and using the touch-screen with the stylus.

On the bottom screen, the stylus could be used to press the keys on the on-screen keyboard or doodle on the pad. The previous doodle could be retrieved, enabling a mean game of tic-tac-toe. The stylus seemed very accurate, and it was easy to spell out messages very quickly with the qwerty-type onscreen keyboard, or even just write them manually.

And, well, that's about the extent of it. A thin or thick drawing tool could be selected, and there didn't seem to be a color selection. It doesn't seem like this would be worth buying for more than a couple dollars, so hopefully it will be a pack-in with the DS.
