Here's desktop OS share over the last 12 months -

* windows share has fallen from the high eighties to the high seventies
* but most of that lost share has gone to OS X - Apple's OS
* Chrome OS is disappointing, having only grown a little (IMO a really good OS for most people)
* Linux is even more disappointing, having barely grown at all
The news is better when you look at other platforms - especially mobile, where Android is the top choice (maybe not the greatest OS ever written, but at least it's not Windows!)
The lesson for me looking at those charts is that choice of OS is basically religion.
The best hope going forward is that the desktop steadily diminishes in importance (you can see this by looking at the "all platforms" charts). The best hopes for prising people away from the grim misery of Windows could be:
1. people find that a "lesser device" than a desktop is "good enough"
2. a cheap desktop which doesn't use Windows proves to be "good enough" (this was the big hope for Chrome OS - but it's only happening slowly)
3. the keyboard becomes obsolete and the concept of the desktop changes (maybe the smart speaker with touch screen is the start of this, and goodness knows why so many smart TVs are still controlled by a TV remote - a device designed to change the volume or the channel of a TV). IBM's PC concept is 40 years old now. When you realise how powerful a cheap SOC is today in comparison to comparable technology from 1981 when the PC was launched, it seems reasonable to ask, "Why are we still using them?"
Writing is the antidote to confusion.
It's not "how smart you are", it's "how are you smart".
Your brain doesn't work the way you want, so train it!
