Just to be clear on what I’m saying, my best educated guesses are
that we will see a new iPhone this summer, and it will be an
iPhone 5S with mostly iterative updates, a choice of colors, and
perhaps the lower-cost model of the latest rumors. But the real
question is: then what?
My gut tells me the iPhone as we know it will be done at that
point. I have a hunch there will never be an iPhone 6, because
Apple will be forced to move into a significantly different form
factor to keep people interested and compete with the movement
toward bigger phablet-like thingies and emerging wearable
electronics (lots of us have fat thumbs, after all). Or, there
will be an iPhone 6 and it will disappoint.
