My last version of Windows was 7. After that I used a MacBook for work for a few years, and I somewhat missed windows for gaming (but mainly used a PS4 during that time so I got by). Then, a few years ago, I switched exclusively to Linux (I’ve usually had a dual boot or a second machine running Linux, but it was rarely my exclusive OS), and haven’t looked back. I’ve since also got a Steam Deck which has completely replaced my PS4, while I also play a few games like Crusader Kings on my Linux laptop.
Gaming is what kept a lot of people on windows over the years, but thanks to valve and the proton team, Linux gaming works as well as Windows gaming (and some people say better than — I certainly don’t have to deal with all the crap Microsoft tries to put into windows).
Some people refuse to use Linux because they’re afraid of having to tinker with it, but that hasn’t been my experience in over a decade. Things have generally just worked for me.
