Since I retired I no longer need to use Win 32 programs. I switched to Chrome OS and Android one year ago this month. I can see that many people have to use a os like Windows because of work or an hobby that requires the use of a Win 32 program, thankfully that is not the case for me. I have used Windows and Windows Mobile for years and hate to say but lm happy that I was able to make the switch.
That's great if it works for you! My family uses Chromebooks, mostly for media consumption. They are simpler and require no maintenance.
I work in IT, and although I don't work in the PC repair department much, I see a lot of what comes through the door. A lot of the business is Windows PCs with malware or botched updates or something. It turns out that most people use little more than the Chrome browser. Something like a Chromebook or some kind of simplified Windows machine would be perfect for them. Windows is still the go-to, however, so that's what they have.
I've said this before, but for most people, using a Windows PC is like using a sledgehammer to drive a thumbtack. Sure, it's the most capable, and it'll do the job. But something lighter would do what needs to be done, and it would be simpler.
Chromebooks still have shortcomings. Printing needs to be done using Cloud Print, which adds complexity to setup. It would be better if they could print directly.
Dealing with photos is still not as simple as with a Windows PC. They will handle them, but it's more difficult to find the local folder where they are stored, and to work with them.
