I use Walk It Out on the Wii several times a week. It's a lot of fun, and I usually tend to exercise longer than planned because I'm enjoying the music and "building" the island.
You can see a sample of this game on youtube.com. It's really cute! There are lots of video reviews of the Wii Fit games. I was intrigued enough that I went and bought one yesterday. Best Buy has them on sale on line for just under $78! I had my game within an hour of purchase by picking it up at my local store. So far, I love it!
