Been using nixos for a couple months now. It’s nice and I really enjoy having all my configuration in one place and able to be version controlled. The down side being installing and configuring things take a bit more time to read how nix does it. I have it on a laptop that I’ve been playing with and removed it and put rocky for something else but I am 100% confident I can go right back to the way i had it.
So far the cons I’m seeing is installing vscode plugins are a little annoying and setting up to do python development on existing projects not very easy.
I came to the same conclusion. If I have a problem that I know nixos can solve it’s useful tool in my belt. But man you try to do anything out side the box the learning curve is massive. Good for those that know but when you only get to tinker a few times a week for a couple hours just getting things to work can be fun at first but gets old very quick.
