Given the rising cost of controllers, particularly when you need multiples to have friends round I wonder when this price point urges someone to write a little app that gets your phone working with your console and thus saving you lots of money. Sure the Nintendo WII also needs an infrared sensor but that could be provided as a cheap add for phones that don't have one.
