While many preffer to use the Keyboard and mouse for PC games there are some out there (myself included) who will occasionally use the Xbox Controller for PC Games, while the debate will continue which is better mouse and keyboard or controller. The Xbox One Controller won't get full PC support untill sometime in 2014. However you will be able to plug the controller into the PC via a micro-usb and use it on ported games from the Xbox One to PC.
