-SD screen, at minimum, Nintendo should of put 720p on it.
-Resistive touch screen, makes using the screen with both thumbs at the same time impossible, waste.
-sound volume on the gamepad is EXTREMELY low.
-dpad placement is horrible
-edit cannot turn off screen while streaming movies without a wiimote, wierd. Does not auto turn off.
