Let me expand on that. Wouldn't it be cool if I could get in my car, touch the phone to the dash, and have the car and phone work out the Bluetooth setup, passcode, address book, etc? Also put my phone onto car mode, with voice controls, navigation, music, etc.
That's what NFC is for to me.
A few months back I installed a new Kenwood head unit in my 20yo car and now I have full BT for making at receiving calls, I plug in my iPhone (3Gs) to charge the battery or listen to music, there is also BT support for music. I have this now and it cost me next to nothing compared to a 2 year contact on a new phone.
The only complaint is the voice control for making calls is not that reliable depending where the phone is and any excess noise in the car. But the up side is every time I get in the car my phone links to it so if anyone calls me I don't have to pick up my phone.
