But we have to put this in the context of an elderly lady who is terribly frightened of breaking the computer and always believes it's her fault when software screws up, because the feedback loop of computers is terrible (either absent, or opaque jargon, or marketing lies). That is, my mother.

And keep in mind that I live abroad. Helping her out remotely is a very difficult and slow process - if I lived close by the story would be different. In that context, when it comes to Windows or OSX, my mother has a lot of people who can help her out other than me - my sisters, my father (they're separated but still get along), some of her friends.

Now, my younger sisters are getting into programming (because all professions need it) so maybe I can get them into Linux too - they're definitely capable but the question is whether they consider it worth the investment. But still.
