NFC is more than just a payment system. Watch this and imagine what you could do with a powerful portable pocketable tablet.......
A day at MIT with NearField Communication - YouTube
I can think of a thousands of way NFC can be used for example imagine movie posters with NFC links to trailers. In store NFC recipe cards. NFC maps. Independent stores with store and website data on the window or ads/posters, tap and add to contacts. all viewable on a 7" HD screen.
I could go on but i will just say, yes i want NFC on my PB :D
