Anybody else use a wireless keyboard?

I got a Logitech cordless keyboard yesterday and it rocks. I like to kick back and put the keyboard on my lap, and now I don't have to worry about getting tangled in the cord anymore.

I use a Trackman Marble, and I tried the cordless model of that, too. It's great for apps, but I can't use it for games because the buttons don't cover a wide enough area and I hate the scroll wheel for games. Too bad there's no corless version of the "classic".
