We've seen Nintendo Wii unlocked in action, and we can confirm that after a small chip installation / soldering job, the console works with copied drives.
The chip costs about 30 € but you will need some skills to install it in your console. The unlock is a few months old and it will help many people to make an easier buying decision.
Wii is by far the most fun way of playing in a while, as it involves some real interaction and exercising. This is the first console that goes away from the PC way of gaming.
