i am not sure what NFC is other than "Near Field Communication", if that is what NFC is what would that bring to the table.
I just received my iPhone 4 about a month ago and so far i like it a lot. I like the size and weight. I think a phone should have some heft to it and the size of this phone fits perfect for me.
The only change i would want is a larger screen but not if it means making the phone larger.
Being able to pay with your phone.
Its widely used in Japan. At all Train stations. I've been to Tokyo quite a few times and still have my Pasamo Card and Suica cards. They are really quick and easy to use.
It would be like an EZ-Pass. Debit cards would be obsolete.
