People keeps talking about size without the perspective of Aspect Ratio. Of coz i suspect everyone were assuming Apple would stick to 16:9.
I really never liked 16:9. Would have loved If Apple were to choose 16:10 or 15:9. And I dont think changing AR is completely off the chart.
If, Apple were to release a Bigger iPhone model, It would either be
1. Sticking to current resolution , 1136 x 640, moving to 4.9"with PPI of 26x. Same Panel PPI as the current iPad....
