You're an odd type. NixOS is for the gratest of Chads, like myself. But you're a level below me, I'm the ultimate Chad using Xmonad configured with real men's pure functional Haskell. You're ashamming yourself using Gnome for fags, so much you have to Ctrl+alt+F2 when someone wants to see your computer desktop. But if you have an anime girl waifu as your wallpaper, then we can forget about it.
Desktops interfaces are not just GUI, it's a style of life.
Nevermind Nix reproducibility pros if you're using it to damage the environment with your dirt rotting Gnome foot while runing.
GNOME is trash because it has an odd logo, extensions break with every update, developers refuse to listen to users, is a MacOS clone (no originality), can't even put icons on the desktop view, is not cute.
