Could Apple be arrogant enough to launch a 4" iPhone 6?
What do you think will be the reaction of the general populace and Wall Street? I'm predicting a single day drop of 10% of AAPL stocks and a large group of people defecting to other platforms at least for one generation. People who leave for other ecosystems may indeed come back after missing Apple's seamless services and the way everything integrates so well, but it will be a rough 12-18 months for the company.
The entire world is already assuming the iPhone 6 to be anywhere from 4.7" to 5.5". If Apple comes out with another puny 4-incher, it will be the biggest troll in recent memory.
