I started using NixOS sort of randomly - I wanted a SteamOS-esque experience for my gaming handheld, and Jovian for NixOS seemed like one of the best options for that at the time.

I like that it's about as close to the SteamOS experience that you can get in a third party distribution, and I like that everything is modular (so you could pick whatever desktop you want to pair it with).

It's weird that _everything_ is configuration in Nix. Little stuff like changing your timezone seems to require a NixOS rebuild (which requires a keyboard). GUI settings clash with the Nix way of doing things.
