> Windows is nowadays required for maybe 2 major things: games (I know, Wine is a thing, but let's be honest: it is very much still a hit or miss)

I'll be honest: I find it that it's very much a hit nowadays, rather than a miss.

With Valve doing so much work around Proton I can basically buy a random Windows-only game off Steam and... it just works. I don't even remember anymore a time when a game I wanted to play didn't just work.

(Of course this doesn't include multiplayer games with anti-cheat. If you like those then yes, you still need Windows.)
