I thought about this before, and mostly agree. My mom knows nothing about computers and could probably use Ubuntu if I stick it on a machine and gave it to her. The thing preventing me from doing it is that when things go wrong in Linux, it often requires extensive terminal usage to fix. And my mother can often find new and creative ways to break a computer. If something went wrong with it, I would have to fix it. There is literally no one else she knows who would even know where to start. At least if she's on windows, she can find someone to help her.
