Get a second gamepad for the price of a game
The Microsoft Store has priced a few accessories for the Xbox One, including controllers, headsets, and charge kits. The standard wireless controller will be $59.99, or $74.99 with a play-and-charge kit included. The charge kits are available standalone for $24.99, and the new headsets -- which aren't included with the console since Kinect is -- are also $24.99.
Not exactly inexpensive, but that wasn't my expectation going in. Considering how much use my Xbox 360 gamepad gets for PC gaming, I'm curious to hear about compatibility details with these new ones. I'd be wiling to upgrade for that improved d-pad, I think.
