I’ll go first, I took my mom’s college textbooks which came with discs for a couple distros and failed to install RHEL before managing to get Fedora Core 4 working. The first desktop environment I used was KDE and despite trying out a few others over the years I always come back to plasma. Due to being like 12, I wanted to run my games on it, and man wine was not nearly as easy to use (or as good) as it is nowadays. So I switched back to windows until around 2015 or so when I spent the next few years trying to replace windows as much as I could. Once valve released proton, I switched fully and have t looked back, unless my still there windows partition tries to take over my computer when I restart it at least.
I installed Ubuntu, ran it for a few hours on a pentium 4 box. Thought it was neat but not neat enough to switch over after I realized I couldn’t play the games I wanted.
I eventually got fed up with windows updates and instability with random shit and developers shitting in the registry and weird permissions issues and all that and switched. Now a days I run pop os on my laptops and desktop with a side rig just for finicky games and windows only shit id rather not configure for my main systems. I have a steam deck too. I’m 👌 close to giving up windows all together but I still like having trash box I can format at anytime.
