I hope that SteamOS finds more of its way into desktop computers. Sure, I don't trust Valve; just like I don't trust any other corporation. But it's like fighting a big cancer with a smaller meta-cancer, if they hurt Windows/Microsoft I'm happy.
Plus its current relationship with GNU/Linux is symbiotic.
I love my Steam Deck, play it all the time and I've discovered new games, that I wouldn't have considered buying before had I been tied to a desk, like Visual Novels, I've played so many in the year I've owned my Deck
