I guess I just question how a person could place importance on a device that doesn't exist yet (in any legitimate fashion outside of rumors) unless there was a number floating around somewhere that shows that iPhone demand is in decline based on screen size preferences. Honestly, I don't see that at all...year in and year out, the iPhone sets the bar as far as sales go, so it seems to me like the preference is with the smaller screen size combined with the other features iPhone offers.
Where is the legitimate basis for the label of "higher importance"? What is the real contrasting factual argument? I don't see "because people are buying bigger phones" as a very legitimate platform because the same could be said about cars, boats, houses, etc...and the fact that people are buying those things has no real indication on whether another product should be bigger to remain "important".
