If you can hold off until August the controller for the new Xbox one slim will do wireless without the need for extra dongles. May also drop the price of the current controller if that doesn't interest you.
And how is it going to do that? not every PC has wifi or bluetooth and i sure can't think of any other ways to get it to work without a dongle![]()
If you are open to going wireless I would recommend picking up the Xbox One Windows Wireless dongle and obviously the wireless version of the controller as the pair work flawlessly.
