Pros
Pro State of the art package manager
Atomic non-destructive upgrades / rollback of a system upgrade / declarative reproducible system configuration / unprivileged installation of packages / transparent source or binary deployment.
Pro Minimal
You can start with a minimal environment and add packages and software to suit your needs as you go along.
Pro Reproducible system
NixOS is configured using the Nix package manager, allowing your system to be replicated and kept in sync across multiple machines. Great for keeping a laptop and desktop in sync.
Pro Robust
Packages don't break after a NixOS upgrade as they are prone to with other distros (especially Arch).
Pro VERY small
Can be as small as about 9MB, and with even X, wireless modules, and more, it takes up only 72MB.
Pro Surprisingly customizable
Fluxbox window manager is especially slick looking all considered, and the options one gets with it's toolbar, app bar, and wallpaper are surprisingly complex for such a small distro.
Pro Use of tcz packages stored on media outside of MyData
Cons
Con Documentation is not good
A lot of the documentation of various functions is buried on the source code, their respective manuals, or non-existent. The documentation, the conventions, and the scattered toolchain really made searching for stuff easily missable.
Con A configuration change might end up bricking your system
Con Not visually appealing
The operating system is not very pretty.
Con Can be somewhat slow to turn on
Once it is up and going it is unrivaled in speed, but it can be sluggish when it comes to turning on, restarting, or turning off.
