"almost everything" did you hear me? several of my favorite titles dont work. these arent little small indie games. they're big AAA games. I'd be willing to admit that Linux has already triumphed over windows if it was just the occasional small title that wasn't supported. but that's just not the case. plus, Valve has been developing steamOS for like 8 years now. they haven't really "just started".

(to be clear, I think the steam deck is awesome. its a huge step forward for handhelds. but neither it nor SteamOS is a replacement for windows gaming yet. neither is any other Linux distro.)

It's way harder to make something run on something it wasn't designed for. It's actually a real feat of programming and engineering that steamdeck works that well. But, as steamdeck gains popularity, guess what, shit will be designed to run on it and will function better and maybe we can get past this 30 years windows lock-in.
