I think it’s safe to say that most people here have used more than one Linux distribution, and their first distro wasn’t their last. I’m curious, what were the steps that took you from your first Linux distro to what you currently use? What were the reasons you switched away each time? Would you ever switch back to an old distro? Are you happy with your current one?
Xubuntu → Linux Mint → Elementary OS → Ubuntu. I don’t consider Ubuntu to be my last (yet) and every now and then I think about returning to Elementary OS, just because it is beautiful.
The reason I keep changing is just to get to know, test something new, see how I deal with it.
