The only reason I stuck with Windows on my desktop machine for so long was gaming, and the last time I tried switching over was 10 years ago. Spoiler: it was a shitshow.
This time, things are MUCH better! The Mate desktop environment is simple, stable, clean, does the job and gets out of your way (kinda reminds me of Windows 2000). Steam's Proton makes running games a breeze. All of my favorites just work. I could even run battle.net as a non-steam game, USING Steam's Proton!
And the kicker? Blizzard's recently opened beta of Diablo 4 just worked. As in, I clicked install, clicked play, and it just worked. Perfectly. As if I were still running under Windows. I've never before seen such sorcery.
So bye bye Windows, except when I'm running one as a VM.
