Remote play is really incredible.agreed.
The PS remote Play app has some deficiencies with playing with a DualSense, but the experience is pretty surprisingly good. I actually feel like the experience is better on mobile than on PC, due to my network set up.
I've been using that mount quite a bit. Really nice alternative if you don't have your PS5 set up to a TV.
I play remote at my in-laws at holidays and even on poorly executed hotel internet on vacation for a few years now. it's amazing how good it is when you stop to really think what the tech is doing.
