I like/love your statement. The problem is, to their detriment, most users don't have the chops to switch to Linux/Apple.(Or the patience.)

Since I couldn't afford Apple at the time, I jumped into Red Hat years age. What a nightmare! But I didn't give up because it was kind of fun. A lot of folks didn't think so. Linux and Apple have made tremendous strides, of course, but if tech stuff is not your thing, you keep financing MS.

On this great site, there's a lot of complicated things discussed, some of which I admit I don't grasp. Many outside this sphere are mostly lost on any tech that is slightly complex, sometimes even if they are helped. One could argue, correctly, that they learn their smartphones and smart TVs just fine. These devises are computer like, but still not a computer. Changing people's minds on operating systems is as hard as politics and religion I've found.

Desktop Linux has been a little bit of a fragmented landscape over time, but I think that what keeps most organizations using Microsoft is that they have someone on staff dedicated to resolving all of these problems for all their users. Most organizations don't ask their regular employees to do things related to setting up software, making sure that they have access to network shares, etc, that's done by a dedicated IT staff that just happens to only be Windows right now for some reason.

Over time the web browser is becoming the only real software that is needed and that has simplified things.

Gaming has helped improve the Desktop Linux space, and Valve is a great force for change there. KDE has decent funding and adoption now.
