Aren't you guys worried about keeping your passwords to the cloud? Dropbox has already been hacked once you know! If we're talking about forum passwords then I can see why one would not be concerned, but if we're talking about keeping passwords to financial institutions of credit card information, it just sounds like you're asking for trouble. Just my 2 cents worth...
With 1Password... the vault itself is encrypted. Hence, even if someone had access to your dropbox account... they can only see the encrypted vault... and your passwords are still safe.
1password uses AES encryption... the same as the world banking system.
