But it does waste a lot of space... there's a lot of duplication of keys (which are deduplicated in the iPhone app), and with other information (somehow I have hundreds of "com.apple.cloudd.deviceIdentifier.Production" in there). And I already mentioned organization fails. Plus it's kinda insecure as it enumerates your accounts exhaustively without asking for a password (although that's not specific to this app). And the interface to view the passwords is terrible. Old and familiar is not synonyms with "good".
