OpenBSD is a great desktop. If you can't live without some proprietary shit, you're going to have a bad time.
I prefer doing most of my work on OpenBSD. I have a windows machine I can use for some garbage I am forced to use and the occasional game. Mostly I will VNC in from the OpenBSD machine.
I think we should normalize using a system that does 80% of computing tasks very well and delegating non-optional stuff to a secondary device. I don't think there's a 100% one-stop shopping solution to a problem as diverse as "desktop utilization patterns".
Something... something... freedom.
