I use a Deck Legend and a Logitech G9x mouse, but when I've got it fed to the TV in my living room I gotta go wireless, so I use the GX120 (I think) bluetooth mouse and keyboard.

And a wireless 360 controller for Windows.

At work I use my old IBM model M. Not only is it the most reliable keyboard ever made, it makes TONS of noise, so anyone walking past my desk can clearly hear me typing away, completing the illusion of productivity.
