Yes, I totally agree in that specific use case it is really great. As written in a different comment, my mom has been running Linux Mint for 9 years with absolutely no problem, because she doesn’t use it for other things than email and browsing. She never had to touch the terminal and everything just works.

On the other hand I have a friend who was sick of Windows and I convinced him to start using linux and of course nvidia didn’t work out of the box. Then there are some compatibility issues with x11 and certain nvidia gpus and with wayland for other gpus - I didn’t know this before installing. So after installing and leaving I basically left him with a laggy mess. So we had to figure out how to fix that. He also have very few ram and during the install we only setup 1gb og swap - which was what the setup recommended. Then after I went home we had to figure out how to increase his swap size. Again this was my bad.

But what I am trying to say is that as a normal person going blind into linux, they would experience the same hurdles and not knowing where to start looking for solutions. So I really don’t think it is ready for mainstream use - unless we as friends and relatives are willing to act as tech support for whoever wants to transision.
