It's been interesting watching the re-releases of various devices trying to emulate classic hardware, either with a SoC or just entirely on ARM but attempting to be faithful to the originals.
But this looks like another kind of fun, if I understand it correctly.
What draws you to different distros? I get my thrills switching between GNOME and KDE on Debian every now and then ;)
I guess you'll get good at isolating your dotfiles and other configuration tweaks.
I went back to school to get a teaching certificate and taught middle school for three years, a couple of summers at a high school, and three more years as a college lecturer (aka adjunct).
I'm back in tech now, which took hard work getting up to date. I was out for ten years and basically missed a whole lot, such as containers, cloud as the path of least resistance, and React. On the other hand, Linux and Python haven't gone out of style.
I enjoyed my time teaching and the perspective gained. I don't regret it, and I did learn more about my own strengths and weaknesses.
