No, I'd certainly not compare a web service which nearly everyone uses - and for many is the only reason they have an internet connected device in the first place - with an encryption technology practically no-one uses.

Someone here suggested that "PGP isn't too hard - you just need to spend 30 minutes studying cryptography before you use it" which pretty much makes my case for me!

I'm sad that we've gotten to the point where asking users to make a small investment of time makes a product basically a non-starter. There's such a thing as too much convenience.
