We all know that from a technological point of view we should be satisfied. But don't you think we should spend some time in "spreading the word" and teach people that encryption should be considered in our life as a concept? Until we don't let people understand how important encryption is, all those tools out there will just waste space on hard drives. I think the culture of encrypting documents and communication in general is missing. Until we don't have that culture all the technology that already solves the problem is useless... or better... unused.
