Steam controller is in its own league, but hell, even the PS and Nintendo controllers have supported gyro control through steam for quite awhile. The Xbox controller is finally advancing past 2003, and into the modern era.
Yup. That and, if a little more distance or wireless is needed, you can remote play to android/ios devices via PSPlay w/ dual sense and 3rd party controller support.
This is basically the non-techie or expensive taste version of the remote play experience as the WiiU screen added more functionality than mirroring.
