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 like iPhone/Safari (granted, not a problem specific to this app). And the interface to view the passwords is terrible. Old and familiar is not synonyms with "good". However now that comex pointed me to the Password in the "System Settings" app, I at least can use it and it's fine if Keychain is left as is.
