@BeAware I will say that the DualSense controller is really something special (re: the haptics & force feedback and all). And it tends not to play nice & give you access to all of its features (wirelessly, at least) with anything but a Playstation.
This basically gives you a DualSense while streaming, where it's not possible otherwise.
All of that said, I'm buying a Steam Deck instead. Because I can do more than stream just PlayStation.
