Just to let you know, you can make your PS3 controller work with a computer, but it's not got official support..

Please let us know if there is more up-to-date software for doing this, becuase when I tried this, it was annoying having to disable driver signing every time I booted Windows :/
EDIT: You can use an Xbox360 controller with a computer too, but I've never tried it.
