With the original iPhone's marketing, the question implicitly being asked and answered was "how is the iPhone better than my feature phone / BlackBerry?"

With the iPhone 6's marketing, the question implicitly being asked and answered is "how is the iPhone 6 better than my current iPhone?"

At this point, there aren't that many potential iPhone 6 customers in the US who still don't know what iOS feels like.
