xbox one controller wireless technology

First of all, Microsoft released official PC drivers that allow you to connect an Xbox One controller (they're all both wireless and wired) to a PC using a micro-USB 2.0 cable. The drivers are on Windows Update at the time of this writing (July 2014), and using the USB cable seems to turn it into a pure, no-batteries-needed wired controller. It is also said to be compatible with all existing games that work with the Xbox 360 controller.

From a speedrunner's perspective, the reduced dead zones on the joysticks, the wired responsiveness (I used to use wireless 360 controllers), and the more comfortable grip are awesome features of the Xbox One's controller. Oh, and the D-Pad. The D-Pad is amazing, wonderful, and a huge improvement over the 360's, especially if you're fond of Nintendo's D-Pads (they're very similar).

I'd recommend trying one of these at a local game shop before buying here (Amazon's price is notably lower) to make sure you like it. It feels different from an Xbox 360 controller, so if you're coming from that it might be feel a bit weird at first. For me, the Xbox One controller is definitely more comfortable than its predecessor, and I only wish it were backwards compatible on console!
