I heard about the Wii Fit when my friend and colleague who writes for Ars Technica wrote about the device at last year's E3. It's basically a new peripheral and "game" for the Wii that helps you work out, tracks your progress, and has a bunch of other fun balance games, watch this video: We talked about the Fit today at work and I think we've resolved to get one, but I think that I'd like to get one for home too. I've heard mumblings about it being release in either January or February, but there's nothing definitive yet.
