Are you a fan of the Xbox One's controller? Wouldn't you love it if you could go wireless with it? Nah, me neither, but that's besides the point. Microsoft has finally taken the time to release a wireless adapter for their current controller. Projected to be $25 USD, the adapter will yield one drawback; It's only supported by Windows 10. And while Windows 10 will be a free upgrade to those currently using 7, 8, or 8.1, it still limits those who may be cautious about upgrading. Polygon confirms it's not for marketing reasons, but I'm not quite ready to believe a simple wireless adapter can't run on anything previous. I'm looking at you Halo 2 Vista.
