I want what Nintendo are smoking, it's exactly the bizarro tablet/bolt on controllers/base station that was hinted at in various patents:
Too big for your pocket
Flimsy connectors that kids will get shit stuck in or snapped off
Minuscule wireless controllers that detach from the unit, or use a WaveBird like controller
Awkward base station that the tablet slots into
Looks bigger than an Atari Lynx!
At least the graphics look modern for once...
