I recently installed NixOS on my thinkpad z16. I set up a sandboxed pi agent to help me configure it and I think it works great. (I also read enough documentation to understand the nix language).

I hade some issues with the trackpad (worse issues that it not being an apple trackpad ie). I told the agent about the problem. It inspected the config, wrote some scripts for me to run outside the sandbox that listened to the trackpad while I used in as per some instructions, and then proceeded to add a few configuration lines that solved to problem. I was pretty impressed (though I think there were maybe 3 back-and-forths with scripts to run, tbh).
