I love the Game notes app that Nintendo packed into the 3DS. Being able to suspend a game and quickly sketch something that just flew into your head is awesome, even more so with the JPEG export (despite the low quality, but eh, Photoshop can fix that easily). I hope that in the future, somebody releases some sort of art studio App/game/whatever with export features and possibly the ability to do some pixel art.
Something Like Inchworm for the 3DS natively would be nice:
