Re: The rise of "It just works"
I too am a retired systems developer and have been the 'computer man' to a couple of 70+ yr old friends for years. Neither is particularly computer literate and up to 10 years ago, they both used Windows and I would get at least a call a month from both as something had gone wrong - nothing serious but just time wasting niggles. I convinced both of them to move over to Linux Mint and even though both were hesitant about change, quickly adapted.
I now get maybe a couple of calls a year about very minor problems and both are quite happy working on some fairly ancient machinery. When I visit now, the conversation rarely mentions computers.
For basic users, Linux is far more suitable for them. It doesn't keep adding unwanted junk or telling you the weather in Burkina Faso and doesn't malfunction with useless error messages. And if it does go wrong is far easier to sort out.
If I was fixing machines as a business I'd despise Linux as it wouldn't even keep the budgie in millet. As you say, it 'just works'....
