… the real reason in my mind that the iPhone wins is it’s ability to “stay in social touch”. The email, the SMS, the browsing experience has enabled much of the behavior that social networkers have mastered already on the laptop or desktop. It’s not about the technology, it is about how the device helps you socialize.
So the iPhone wins because it both keeps us in the flow and keeps us loosely connected. Perhaps a little like adding a “lurking” factor…. iPhone in hand I have a better sense of what my friends and colleagues are doing.. I am more connected without actually thinking about it or working at it. As someone who’s never used a Blackberry and yet observed the “connected” behavior that creates around email (like IM) it’s been a revelation.
