I didn’t—I like to pick up old second-hand laptops that are selling for cheap and tinker with them (install different OSes, coreboot them, etc). One of the machines I regularly use is OpenBSD, but it’s not my sole OS. My gaming machine is Linux—afaik you’re gonna have a tough time trying to play AAA games on any other (FOSS) OS, but I’ve not tried, because the laptop I run OpenBSD on is an old underpowered Thinkpad anyway.

I picked OpenBSD over other non-Linuxes because of its focus on security. Also I think the pufferfish is cute. It wasn’t that deep of a decision for that particular laptop. I do find it quite an enjoyable OS to use, and I have anecdotally had fewer problems with it than with Linuxes, I suspect because their whole security focus also means fewer bugs.
