I play video games on my xbox and my psp. Also sometimes on the kids NDS, not counting the PC and the occasional firing up of the old Dreamcast or Playstation 1. Haven't plugged the even older SNES in a while, I have an emulator on the psp.
I'm still using the usual controllers though, and frankly I don't see myself using that fitness stuff
My wife uses the Xbox and the Yourself Fitness "game" to exercise. Doesn't need a weird controller, just some weights and some will
I would never be a good customer for you, I hate exercise, it's boring. The only things I do are pushups and abs to stay in some kind of a shape in winter. I much prefer just running on the trails (weather permitting) and seeing some wildlife, or simply play pick-up hockey, baseball or basketball games with friends/kids. It's as good exercise as anything you can do at home, and still a lot of fun.
