An event JUST for NFC?
I am being sarcastic but seriously, bring more to the table. Old technology is not a 'groundbreaking' feature.
Just because a technology exists doesn't mean it's widespread. Before the iMac, PCs had USB ports but it was extremely hard to find USB keyboards, USB printers and USB scanners. By releasing the iMac, companies were forced to upgrade their peripherals or they were losing part of the market.
