Isn't NFC both a developer and consumer thing? As ChristianJapan said above: "Less objects in my wallet and back pack". I most certainly believe Apple has the power to make NFC a success for consumers.
It will be very big, eventually, but the percentage of retail and people who have any clue as to phone wallets now is tiny. I do expect they will include NFC in IP5, but not sure it qualifies as a "big" consumer thing now.
The fact that they have Passbook in the beta is encouraging, but talk to any large scale restaurant owner (for example) about the difficulty in integrating such technology into their existing propritary hardware today.
