Of course, without an operating system, all you have is hardware and other devices. But I meant for the casual desktop user, this does not really matter for them I don’t think. I’m sorry, I forgot to put it in the question. Obviously operating systems must exist, I get that, but I mean that for a desktop user, who treats their computers as bootloaders to the browser, so to speak, will different operating systems be relevant for them, i.e. the majority of users?
