The rumour is that the iPhone 5 will have a 4" Retina Display, why would Apple make the display larger? Assuming that the number of pixels on the larger display stays the same as the iPhone 4 (good for developers), this means that pixels per inch would reduce and that the display would be 'poorer' and should be cheaper to make. Is this either a way for Apple to get more profit, or for them to bring the price down a little while possibly easing the pressure on their supply chain as a lower pixel count per inch should be easier to produce. The Quality question would be whether the pixels be visible to the naked eye, if so, that's a backwards step for a company which prides itself on raising the bar.
