There are always stories of people installing Linux on their parents computer to provide them a more secure and stable operating system, seems interesting to share experiences.
Edit: I’m assuming that parents are okay with the changes, or do not care. Obviously do not force anyone to switch OS if they don’t want to.
I may prefer Mac OSX, but Linux really is a fantastically beautiful - and functional - OS, so I am glad that she can enjoy it better with this!:-)
