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.
My very first experience with Linux was in probably 1993 or so. I ran a dial-up BBS with a Usenet feed and a friend UUCP’d me the first few floppies of slackware to try. I don’t remember getting very far but I had used OS/9 earlier on my Coco 3, so the shell was pretty familiar.
For actual work, about a year later I started working for a dial-up ISP and my workstation was a Linux box connected via Serial PPP to a Sun pizzabox.
I’ve used Linux on and off as a Desktop over the years but always maintained at least one server. In my current jobs there is a mix of Linux and FreeBSD servers I run on a Linux based virtualization platform.
