As mentioned in TFA, running OpenBSD on mainstream, not-bleeding-edge PC laptops is pretty easy. I've been doing it with such machines (Dell, Compaq, ThinkPad, and most recently HP) for eight years. The last few years especially it has been easier to run OpenBSD than most Linux distros, actually. Hardly niche.

OpenBSD has been the most trouble-free laptop install choice I've ever had the pleasure to enjoy, and the smoothest upgrade experience without reinstalling as well (including upgrades of Windows, MacOS, and DOS).
