Thanks for the replies.

What about the Internet connection? The way Harmattan handles them is quirky even to me, so it will probably be even more quirky to the elderly person. They don't need to be online 24/7, I'd say they'll enable the connection rather on-demand.

It's more complicated than the primitive Android-style on/off toggle, still not so clear and simple as the Fremantle settings.

Unless one disconnects manually, the connection is being used automatically whenever needed. Still, once one disconnects, the connection is never used automatically. Is it possible to make all the connections be either used manually or automatically?
