Microsoft's Project Natal - Control the Xbox, play games with your body and nothing else. No controllers. Just you. No thank you - I'm lazy.
Sony's Motion Controller - Seems fun, seems interesting - probably just for a while. Just like the Wii, you just want to try it out and that's it. I'm too lazy to wave my arms, stand up and swing, jump, bla bla.
Me stick to regular wireless controllers. When I play games, I want to relax and barely move, just my fingers only.
All this motion comotion with the Wii, Project Natal, SMC is strictly for young kids and grand nys and pas.
