It makes one wonder. The upcoming PassBook electronic tickets sound great, and I can see why in some cases it would be impractical for the iPad. I also have to wonder about the potential for this to go far beyond just tickets. Imagine going to the store and using it like you would a gift card. For example, I cashed in a bunch of credit card bonus dollars for some gift cards. It took over a week to get them in the mail. What if you could get them sent to your device. Or your relative is able to send them directly to your device from the store with just your email or something. Wouldn't we be able to use them on the iPad just as well? Electronic tickets for travel would be just as easy on the iPad. Opinions?
