In the end, I don't have the time or the patience to struggle up from being a new user to being a power user again, particularly as even to get into the user position I need my wireless card to work, which means that I need to be a power user and be able to install it. In the end, Debian is too difficult for me. I'm sure that Windows is a much inferior operating system, but I've been using it for years and I quite like it these days. Most problems that come up in Windows (except that of getting my home computers to talk to each other) I can solve or find a livable workaround. To proper geeks, I probably sound like a prisoner who's forgotton what it feels like to be free and so doesn't miss it but there you are. Sure there are things about it that bug me, but that's par for the course with computers - there are no systems which don't have their irritating quirks. They're all designed by people, that's what you get.
I still consider the idea of buying a Mac one of these days, but I'm shy of that too. What if I find MacOS as difficult to come to grips with? It would have the advantage I suppose of being widely supported at the non-geek level, which Debian, in my opinion, isn't but still. What I really want is to be able to have a trial period on a Mac to see if I could get used to it but I don't think that's exactly feasible. I like the idea of moving but only if I don't have to re-learn. I just don't have time.
Yikes! That gave me a shock! I just ran Windows update and got a new display driver. Which reset my screen res to 800 * 600 from 1600 * 1200. Still, once switched back, all seems fine.
