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 didnt have access to good internet, this was back in dial-up era in the 90s and even though my pals had 56k, I was still on a very spotty 33k modem. I bought “Corel Linux” on disc(s) from Costco. It wasn’t particularly great, but I definitely learned a lot about getting linux to play nice with hardware!
