Potential new iPhone looks plausible to provide a range of sizes.
Marco Arment does the math for screen sizes that aren’t disruptive for IOS app developers.
Which one would you prefer?
Seems to me that likely most popular combinations are:
1. current small iPhone with full size iPad ( I am quite happy with this combination of sizes)
2. current small iPhone with iPad mini ( a lot of people seem to be going for this)
3. iPhone plus with full size iPad (going with largest highest quality screen for each model)
May be less likely that people want the largest iPhone and smallest iPad together because they are close in size?
