This feels more like a generational thing or something because if I mention to my co-workers or friends that “my desktop isn’t working” they don’t think “oh your steam deck won’t go into desktop mode?” No, they think “That big block computer with a large motherboard isn’t functioning properly?”
en.wikipedia.org/wiki/Desktop_computer This thing. So when I say “Desktop OS” I don’t expect anyone to think anything other than the OS that runs on a desktop computer.
