some people were/are hypocritical about this, so what? happened to me before and probably happened to you as well
I'm very fond of the concept of motion controls, but I feel they still need to mature quite a bit.
When I was playing some Wii games and while watching the presentations of PS Wand/Gem and Natal I noticed quite some nasty input lag, which most definately would spoil the experience to me (I'll still give Sony's version a try), so I personally don't expect to really be able to enjoy the input method until next gen or the gen after that.
