OpenBSD is not your typical consumer desktop OS. If you expect it to be similar to linux / windows / macOS your not going to have a good time. As a unix workstation however it has its place.
Certain things you might take for granted around hardware (The author mentions Wireless on intel AX210 and a bluetooth stack) are missing or in a poorer state then you would find on your "typical desktop" OS. Additionally there are plenty of Linux apps that will make dump assumptions that they are running on linux.
Things will generally be a lot more manual to setup rather than auto-magic. OpenBSD is focused on software correctness (security / reliability) over all other attributes (performance, features, ease of use). As part of this there are natural additional focuses on simplicity (to make it easier to be correct). Thus OpenBSD is rarely going to be the first with something that isn't security related.
If your workflow is heavily UNIX based, then OpenBSD can make an awesome Workstation OS. If you work on open source, you will have everything you need. However if you work with other people on other platforms you will see incompatibilities, such as being limited to web based versions of Collab services (discord, teams, slack).
I tried it a couple years ago, the laptop I tried it on was underpowered (4GB memory, Skylake m3 - it was a Chromebook).
The core software worked great. I could mostly rely on the base system for critical software, I found cwm entirely sufficient as a window manager, xterm is obvious, even nvi is very usable as a text editor. I did use mutt which isn't in the base system.
I did however find that there were no performant web browsers, though this situation may have improved since. Chromium was the best option at the time and it worked okay for simple pages, but struggled for complex content. I also use both Spotify and VS Code typically, and whilst the former is easily replaced with ncspot now, I don't think there is a vscode/vscodium port. I suspect if you don't rely on any Electron applications though you wouldn't have any issues...
I'm glad to hear that. My experience was a little over 3 years ago so there has definitely been a bunch of time for the situation to improve. The laptop itself was also pretty weak.
