The Xbox 360 Wireless Gaming Receiver is one of the hidden gems of PC gaming -- it lets you play loads of Windows PC games from the couch with controllers you already own. Later this year, a $US25 dongle will let you do the same with your Xbox One gamepads too!
Sure, you could already use Xbox One gamepads on PC by plugging in a really long USB cable, but who wants to do that?
Besides the obvious ergonomic improvements and the Xbox One gamepad's vastly superior trigger response, there could be some fringe benefits as well: now that you'll be able to stream Xbox One games to your PC or tablet, it'd be nice to have an Xbox One controller on the PC or tablet end of that arrangement so you can control them properly too.
Oh, and it just so happens that a new version of the Xbox One controller (also shipping in late 2015, or in a bundle with the dongle for $US80) will have a built-in headphone jack so you can theoretically listen to your PC's audio with your favourite pair of wired headphones. Sweet.
The only thing stopping me from buying one is that I've already got a Sony DualShock 4. With the right app, it's also a damn good PC gamepad.
Microsoft also announced a new 1TB Xbox One today, and a permanent price drop for the existing 500GB Xbox One to $US350.
