I just click "Install" and then "Play" in Steam on my non-Windows machine. I guess you can't play Fortnight or whatever, but it works great for me.

Playing 20 or so games on my Steam Deck I had to edit one only .INI. The Steam Deck is the only device I've ever seen that pairs perfectly with AirPods every time, it beats Apple devices.

I also have a big gaming PC/AI development with a NVIDIA GPU and, yeah, NVIDIA's app to maintain drivers is a little skeezy but I just download games on Steam and they "just work" though I am not really a day one kind of gamer unless it is a new Dynasty Warriors or Fate game.

I'll grant that kernel anti-cheat sucks, if you play that kind of game and cheating bothers you well then... Maybe a locked down environment like the PS5 is a feature and not a bug.
