What's interesting to me about the iPhone ecosystem is it has large sociological impact. A computer in your hand and all that. But lesser considered is the changes in daily behaviour in how you interact with the device. When you have millions of people simultaneously changing habitual behaviour and in concert with each other, it gives them a sense of community of a style that has never existed before. Not religion. Not geography. Not politics. Behaviour. Discuss.
Seriously. iPhone is a cultural phenomenon. Pretty cool to see.
