Query: Epic fail for PC users

This controller does not work with Windows. Please stop posting that it does.1. When I opened it I thought surely it would come with a cord to connect and charge over USB. WRONG. MS can't afford to give you a cord. It takes AA batteries.2. Ok so no cord, no big deal, surely it uses a standard USB cord I can just plug in like a PS3 controller. WRONG. It uses a proprietary connector designed by NASA.3. Ok so no cord, well surely I can download the software and pair it since it uses bluetooth. WRONG. It uses a proprietary communication system designed by NASA. You have to purchase a special receiver to use it.Three strikes and it was in my trash can. Not worth the hassle to return to Amazon. People wanting these for their PCs need to order the "Xbox 360 Controller for Windows". Those are not wireless but should come with a cord.
