Tomy's My DoItAll may not be the most anticipated title on the DS, but it's kind of perfect for the Nintendo Channel's DS demo service. We're totally curious about the kid-friendly personal organizer "game" and its suite of activities, but not "pay money" curious. Now we can check it out for free, with no risk other than the possibility that we'll find it awesome and be forced to hide our enjoyment of a children's non-game from our Joystiq colleagues.That's the only new demo on the North American Nintendo Channel this week. If you missed the Big Bang Mini demo, it's back now, and we don't mind broadcasting to the world that it's worth checking out. The full list of available demos and new videos is after the break!
