Yes, and the very few games that really tried to make use of the interface were amazing. Zelda Skyward Sword was incredibly fun. I remember slashing around thinking there was no way we were going back to regular controls from then on, but I was wrong. I think we have invested so much in the current controller layout that it's difficult for new ideas to get off the ground.
Ironic you mentioned that game is being the Pinnacle of motion controls, I'm fond of Wii sports resort instead, that zelda game made me wish they had GameCube controller support because it was so inaccurate.
