The novelty of motion control quickly wore off for me after a couple of days of Wii bowling.
Since "novelty" means new, perhaps Wii bowling was a novelty, in the same way "Stanley Steamer" must have seemed novel, as is all emerging technologies. I'm not suggesting Kinect will be the breakthrough product, but it has promise in a transformational way in the world of digital media. I hope Microsoft executes well on Kinect, and that competition really pushes motion control to a new level.
To reduce it to annoying contortions is to miss the real potential, IMO. You may not like it, but I think many will.
