If Guitar Hero peripherals count, than the Xbox 360 Guitar Hero 3 guitar.
If not, I was using some generic Gamestop-brand 360 controller on my computer for a while until I finally replaced it with another generic controller.
It might be worth noting here that I also don't use a mouse; I use a trackball. I've used a Logitech Trackman for over 20 years now. I still remember when mice weren't the default point-and-click for computers and they didn't usually have scroll wheels...which is important, because my trackball doesn't -- there's no reasonable place for one.
Only the exceptions can be exceptional.
