Sorry to say this, but IMO the pointing capability of the Wiimote is toy quality, nowhere near proper videogame controller grade. I don't enjoy saying it and I am happy Nintendo is doing well, but as a long, long time videogamer that is my final veredict on it. I will not sell my Wii because I'm convinced Nintendo will manage to make great games despite that serious flaw, but to me this is not a real revolution.
It feels a bit like when after having learnt to play at the arcades, quickshot made popular the airplane styled joystick, which simply couldn't properly make diagonals, both for the disaligment and the poor build quality. A piece of crap, but a succesful one indeed. Everybody bought them and other manufacturers copied them because people found it cooler... During years it was almost impossible to buy a decent joystick for the 8bit and 16bit computer. The "great" NES pad, wasn't great if compared to a real arcade quality joystick, but at least it allowed for decent game control.
