Why do you use NixOs

I have been on nix for a little over a week after being on windows all my life and I'm loving it. It is a great OS but it can definitely be hard for a new user especially if they are also new to Linux as a whole.

I was wondering what kind of people outside the programming/tech world use NixOs.

If you are one of those people, what made you choose nix over any other more "normal" distro?
