Tim Cook Says Current Tradeoffs Are Not Worth The Bigger Display
During this evenings earnings call, Apple CEO Tim Cook was asked on Apple’s thoughts on a bigger display on the iPhone to allow them to compete with their competitors such as Samsung. Cook’s reply did not suggest s that Apple currently has a larger screen iPhone in the works and do not plan to do so until their is no tradeoffs.

Our competitors have made some significant tradeoffs in many of these areas to ship a larger display. We would not ship a larger display iPhone while these tradeoffs exist.
