Nobody in my life even notices when they change their 'primary operating system.' They buy a phone based on what looks cool at the time, sometimes it's android, sometimes it's iphone. They move freely between chromebooks, windows, and mac os, because everything is online anyway. It's only 'experts' who have trouble with this.

Partly agree. I once installed Firefox with uBlock Origin for someone who was Chrome user on an old PC and complained it was slow when browsing, and they told me that they didn't even know that there were different browsers available.

I'm the IT guy to most of the elderly people in my life, and steadily switching them over to Linux Mint over the years. Fact of the matter is, most of them use their OS as a gateway to their web browser, and don't care to do anything else with it. For many non-technical users, switching OSes is literally a non-thing. The only difference vs Windows is that they call me for assistance way less frequently.

you are telling me that everyone in your life freely swaps between windows and mac without even noticing a difference? no problems?

i call bullshit. i have worked in very big orgs. changing a single icon can cause a deluge of support tickets.
