I agree. One can just install Linux Mint or Fedora or anything and then Linux is just as friendly to use. You got a desktop, you can use your mouse to start up the browser, install applications with a mouse click, and so forth. You could do without opening up the terminal. Functionally the same as using Windows.
I would like to see many non technical people doing that, and then their experience trying to watch Netflix, Prime, HBO, YouTube,...
Linux experience is ok, when one knows UNIX and is technically skilled.
My parents, and my wife's parents, have been doing just that without any trouble whatsoever.
Just browse to netflix.com and log in. Not any different than in windows.
My parents use mail, firefox and libreoffice writer. That's about all they need and it works fine and is way more stable and hasslefree on linux than when it was when they were still using windows (admittedly quite long ago).
And if you are talking about seeing people install the OS, people can't do that for windows either.
Pretty much my experience too. Not just with my parents but with many other adults too.
