Kasceis, i understand distance isn't a problem. Using the Wavebird isn't [just] about distance. It's about freedom. You'll use it like any wired controller, at first. Then you'll realize that you can get into any position, and not have a cord draped over you. If you're like me and have all kinds of crap (CDs, cables, papers) on your floor, you'll appreciate just being able to pick the Wavebird up and play, instead of fishing through a sea of stuff.
It's the little things, but for most of us, they really add up.
