The difficulty of using OpenBSD has been highly overstated. If you’re used to Arch Linux you will probably find OpenBSD pretty easy and probably much less tedious lol. It actually is meant for desktop use. A basic graphical environment comes with the system and the installer will ask you if you want it to run at boot. The availability of desktop-related ports (BSD word for third-party packages) is quite good too. I run OpenBSD on my desktop and everywhere else and really like it, most of the time lol. OpenBSD is meant to be really easy to set up and for everything to more or less work out of the box with good default settings.

One thing that tends to trip up new users is that the resource quotas for the default login classes (users are separated into different classes which have different capabilities) are quite low, so if you see programs running out of memory or not being able to start new processes, just raise your limits in login.conf. There’s a manpage about it. OpenBSD has great documentation.

If you decide to try, let us know how it goes!
