Microsoft's Xbox 360 controller has dominated the PC gamepad market during this console generation. Now that we're nearing the launch of the new platforms, dedicated PC gamers are starting to worry about which gamepads will work going forward. This week, Microsoft officially confirmed that the Xbox One controller will work under Windows, but not until sometime in 2014. While this is positive news, it still leaves PC devotees wondering why Microsoft can't make it work on day one.
