I know this may sound like a slight but it isn't, but #OpenBSD feels like retrocomputing with modern technical capabilities and security advancements, many simply leading the way.
I say retrocomputing because hardware to run it is limited (Thinkpads and other laptops/desktops where you're certain the drivers exist for it, especially graphics and wireless cards). I have an X1 and it works amazingly. May get a Framework laptop in 2024 for it to have something that's more metal, sexy, and less fragile.
Also retrocomputing because typically software available for GNU/Linux or even FreeBSD is lacking. I have a growing list of things I want to work on new #ports for, hopefully this weekend.
BUT security and correctness in code are important to me, so certain sacrifices/compromises must be made for the greater good... and let's get real: I spend most of my time in a terminal or browser anyway. I'm mostly lacking programming libraries and #Mudlet I need to port over (I started doing it for #NetBSD a while back in WIP #pkgsrc, IIRC, need to find that, too.
