So what is this ad (and the previous ad) saying?
Basically it's a testimonial ad, but presented in a touchy-feely way.
It makes the claim that every day more people throughout the world use the iphone for taking pictures and listennig to music than any other phone. It helps that all these people are incredibly cool and young looking.
But more importantly what it concentrates on is human interaction. The iphone almost disappears into the background making it an essential but almost invisible companion for human connection. It brings people together in ways we all would like to interact.
A few (cool) grannies and it would have been perfect.
