I know you didn't ask about Windows users, but assuming you are from Apple and have an ear there, please forward this message to the appropriate individual...

Please performance-profile iTunes before frustrated and contractually-obligated-to-use-iTunes iPhone users slap you with a class-action lawsuit.
