I love NixOS because it lets me configure my whole computer with a configuration file that's a functional program and because it ensures the atomicity of configuration changes and software upgrades. http://nixos.org/nixos/about.html http://nixos.org/nixos/about.html In my view, it really is a fundamental improvement and represents the state-of-the-art in OS distribution. Nix, the package manager, also works on other distributions and Mac, and operates in a totally self-contained way. It also lets non-root users install packages for themselves. NixOS doesn't have a graphical installer or anything like that though, so at the moment it's for enthusiasts. But there are tons of packages and they are easy to make and change. And the community is friendly and smart. I've been using it since spring 2015 with few problems, and I absolutely love it... it's basically made me like computers again. I run it on my Dell laptop and on an Amazon VPS, sharing parts of the configuration via Git so that all the vhosts are available on localhost too. I also sync the main configuration file with my brother/cofounder so our laptops work the same aside from our own user configs. For example, he might create a new service that depends on some packages, changes some configs, opens a port, adds a new Unix user, etc etc, and when I pull his changes from git and run nixos-rebuild, all of those changes are applied to my computer seamlessly and atomically.
