The Nintendo Wii which has gotten a lot of good press for getting people up and moving playing games such as tennis, boxing or bowling. This extends to children, adults and even seniors as many old folks homes engage in what is being dubbed "wiihabilitation."

For $89.99 the Wii Fit balance board and game disk can be yours, if you can find one. They seem to be sold out already and the price is already climbing.
