I tried FreeBSD many years ago (back when I was on dialup and bought a book with the FreeBSD install CD included…).
At the time it was interesting to tinker with, and I did use it as a dual-boot on my Win95 computer, but I moved on to Linux when Knoppix came along.
At the time linux seemed more end user friendly.
Maybe I should spin up an install just for nostalgia sake, and to see where it’s at these days.
I’ve used old laptops as battery backed up NAS boxes.
Obviously assumes that you can install a reasonably large drive and that the battery still has some life left in it.
