Fair enough but for that to imply anything about 'most android devices having large screens' you'd need to show that most devices in the < $300 group also have large screens.
The existence of one such device that is known to have sold poorly, even though it was a good product doesn't tell us anything about that group.
Apple's documents do not show that most Android phones have large screens. That is the original claim you made.
40% of the growth came from phones > $300 and > 4 inches. Only a couple more million units > 4 inches is required from the < $300 group to be the majority. Apple's next phone will have a larger screen because that is where the majority of the growth is coming from.
the nexus 4 is 5 inches and < $300 by the way. 4 inches is quite small in todays market
