> I like how slim and simple it is.

I ran OpenBSD on my laptop 22 years ago. Back then, a full GUI environment with terminal, web browser, editor: 28MiB of memory for the whole operating system and user environment!

About 10 years ago we moved offices, and I was over checking out the new internet circuit and cabling in the office. The circuit was up, and I hadn't brought anything with me to connect to the network, but we had already moved some boxes of old stuff over.

I found a 10+ year old Dell Pentium III laptop in one of the boxes, installed OpenBSD to do some simple connectivity testing, and ended up with a full workstation install and using it for network monitoring and some other random stuff. It stayed in the network/server closet until we moved out of that building just a few years ago.
