Hopefully this will be answered in the upcoming Passbook hands on demo on the Apple site BUT... It occurred to me that we need the display to stay on longer when using Passbook or possibly stay up until dismissed. We cannot have the display go off when tilting it to be scanned by the Starbucks app or when getting through an American Airlines check in. I have already decided not to bother using it for airport TSA security because I am going to have to take it off immediately anyway for the body scanners. Anyone already know?
