Yeah back then I was in elementary school. I chased single percent performance gains from bleeding edge because I couldn't just buy better hardware. If you wanted the latest versions of anything ubuntu couldn't do it without iffy unofficial repos and dependency hell. I did it anyway and it sucked.
Wait wait... if you had an old ass computer, why did you need the bleeding edge stuff? That doesn't make sense.
Also, I'm still skeptical about immutable distros. I like being in control of my PC. And I'm too old school I guess.
