This is an early question, because the 5s is not in stores yet, but I'm curious how potential customers will be able to test out the Touch ID sensors on the 5s. I'm assuming that will be testable, to help people decide if it is something they want on their phone. Seems like a logistical nightmare if the typical throngs that hover around the tables have users that are spending 5 minutes setting up their ID. In addition, someone will be forced to stay at or go back to at the same phone to do further phone testing, because only that phone will remember their print. Supposedly the phones only hold a certain number of prints too. And are people going to worry that their fingerprints are being stored (that is moot, but they still may have to reassure people). I really want to test out the sensor (I don't care about security, don't use a lock screen, but I do want to avoid slide-to-unlock) but I want to know how many months I should wait until the crowds die down. Or maybe they won't allow testing of that feature. Anyone have any ideas?
