To accompany the launch of PSNow on PC, Playstation has introduced an adaptor that let's you use a PS4 controller to play games on the go via PSNow or with games via Remote Play (play PS4 games streamed from the console on your PC/Mac). Previously, you had to use a USB cord with your controller.
Interesting to see Sony continuing to branch out their offering to other platforms, perhaps implying that PS VR might have a home beyond the console as well.
