@darth #openBSD - to give some indication of how simple the installer is: I installed it myself and I'm using it as a daily driver, and I'm such a noob I haven't figured out how to mount a USB stick yet. Seems very secure indeed 😀 I managed easily to give it a GUI, office suite, web browsers, #freeCAD, #GIMP, #nextcloud client, & #flightGear. As a computer ignoramus, I'm really impressed by how easy it is. One day I will understand the disk partitioning too 😉
One cheap Chinese laptop worked fine except for the trackpad, another one has to be left overnight to boot up (the text-only installer boots swiftly so I guess it's most likely an X problem) and the WiFi card isn't recognised. Moral of the story: you'll probably have an easy life, but probably get a thinkpad if you want some degree of assurance.
It's like art to me: I don't understand it the way the artists that made it do, but when I see a system as carefully documented and thoughtfully constructed to be as elegant as technology seems to permit... Well, I feel like I know it when I see it!
