The software add-ons have the potential to turn the iPhone into the pocket computer of the future, as essential, Apple hopes, as the keys in your pocket or purse.The reason we put things on our key fobs is that keys have, until recently, been the locus of our identity. We use keys to get into our own private spaces (home, office) and shared areas. So we keep them on us all the time.
The phone is the new locus of our identity. I don't know about you, but my phone is on or near me all but 1.5 hours per day (they don't allow them in the gym). I stow my keys in my luggage when I travel, but my phone is on me all the time. Keys represent access, but the phone represents communication and self-mediation, connecting me to all of my contexts and contacts. I suspect that's already true for many people, so the line from the USA Today piece seems a few years late.
