What am I missing that Mailpile will do, aside from possibly a better interface and lots of marketing?
Jk, the main difference is that mailpile wants to be fully web-based, whereas Enigmail is a fat client. I guess they plan on working heavily on key generation and storage (which is typically the sore point in tools like Enigmail).
