I'm looking at their docs now...

I worry about Dropbox + security. The fact that I'm sharing folders publicly with other people in the same directory that I have private data, worries me. Lots of room for human error

Why does 1Password need dropbox? It would make much more sense if they had their own cloud solution

Edit: Don't get me wrong, I love dropbox and I'm sure 1password is great. But I don't feel secure with dropbox (ever lost a file that was in your dropbox because you or a colleague made a mistake on a synced computer?) and I hate the idea that a person could have a copy of a single file with every one of my clients critical passwords, encrypted or not
