You said:
“...that the Microsoft Surface software will NOT be updatable to Windows 10”.
That is not true.
Looks like deadend hardware and software, from Microsoft.
You are obviously superior to me, in your technical computer knowledge.
I am a mere consumer and user.
Apple has proved to be the superior company, in terms of serving the wider base of non-technical users these days.
As a mere nontechnical user, I have found it annoying to have to learn the changes, with each Windows version’s “improvements.”
I note about half of their versions are duds. If I had invested in Microsoft, I would be concerned with the ratio of their duds.
Others may like to play with computers, as a hobbyist. I got over that very quickly.
