from an IT perspective NixOS would be VERY easy for them to setup. pretty much clone the same configuration across all computers and you're good to go. PLUS if they installed comma with it would make the user experience easy. just have to teach people to open a terminal and type ", firefox" and you're good to go. keeps things clean. don't have to worry about people installing stuff that could potentially break their system as you would just lock down the nix configuration.
