Prototype Xbox 360 Controller

I owned this controller for a brief period of time. It is an early Xbox 360 controller, wired version. It is actually quite different from the retail 360 controller. It lacks the guide button, the buttons are completely different, the d=pad is white and a bit different, and even the joysticks are different. Even the plastic it was made out of is a bit different, consisting of a much smoother, white plastic.
