I did say "non-technical", which is open to interpretation, but I did not mean 'computer illiterate' (i.e. only uses apps given by OS).
The discussion here is really about average users, and the baseline assumption here is that we are talking about apps that don't come with the OS, that we'd install, since we're devs, creating new stuff.

It's a French or power-user thing.
