RedHat and Ubuntu both provide enterprise support.
The app is similar to what’s going in on windows.
Where that becomes frustrating is when you have a computer that isn’t well supported by Linux, things don’t work, battery is bad, you have to look up for ways to fix them and so on.
But if the « driver » support was as good as on windows, people could switch in 2 seconds.
My university computers ran Ubuntu, we were not computer nerd but civil engineering yet everyone adapted very quick.
You don’t need canonical enterprise support.
If nothing is already broken, Ubuntu isn’t that different from windows. You got your 10 app icons, and a button to shut down the computer.
And the file path ? Everyone used the standard file picker and had no issue. I guess it defaulted to the home directory or desktop, whatever the case we just put all the garbage there in folder like we used to do in windows.
The previous time he meaningfully interacted with a computer before that was via punched tape containing ALGOL in the early 1960s. (When I first manually "decoded" those tapes 30 years later in the 1990s, it kind of blew my mind. I had just learned Turbo Pascal. Looks very similar at a high level.)
