A Treadmill for Tots

Yes, you read that correctly. They now make treadmills, stationary bikes and who knows what else for kids. The one that I just found at Target.com is made for ages 4-7. 4-7? What's wrong with kids running around in the backyard? I guess this can always go in front of the TV? Do you know anyone who owns one of these? Honestly, I really don't see a problem with these..I am merely surprised that kids need this.
