The problem will all come down to UX. * Key generation and exchange is a challenge. Most people I have taught how to use gpg / pgp can't seem to figure out how to publish there keys, send or receive keys. * Entering your password often is a pain. Most people I have taught have given up using this on a day-to-day basis because its just such a pain. As an aside, there's the problem of improper use. Right now there are too many choice as to how you can setup pgp leading to the problem of people using it wrong. And don't get me started on private key security. Most people do NOT want to think about this. Quite honestly, I agree. Something needs to be done to make it very hard to compromise your own private key.
