Actually a non-issue as I just upped my expired passport (book) and also got the 'passport card' for land travel only Mexico or Canada. The book is still required for air travel. In my work (armed) I'm often asked for ID by a nosey peace-officer and the passport card is most useful since they don't know how to 'run' it yet and you are not required to surrender it as with a driver's license. It shortens the non-consentual interview considerably! Unlike England, where a man living in his own land is not required to carry an ID, we in the colonies (sunny CA) are practically required to do so to prevent stop and frisk detainment.
