The amazing thing about modern gaming consoles is all the different uses that people put them to. You don't just buy gaming consoles to play games these days.
Well, most people do, but I've seen articles by people who have used them to help surgeons in surgery and train fighter pilots. My mother uses her Wii to do exercises and weigh herself to track her health and as it says in the article you can use them as a blue-ray and DVD player as well.
Now that they've put those motion tracking features into different consoles they've become capable of doing so much more than just playing games and I think that once people start getting really creative with this technology we're going to see some amazing things.
