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’d used Linux in VMs since the early 2010s, though only really for curiosity purposes and never did much worthwhile. Got a job that uses Linux pretty extensively back in 2016 and by 2019 once I’d noticed proton was a thing I was using Arch Linux on my own laptop. Distro hopped several times in the following years and now on a new PC I’ve decided to just stay on Debian bookworm and just keep applications up to date using flatpak.
