It occurred to me today that if the idea of a Retina-display 7.85" iPad at 1024x768 was, at least mathematically, feasible then what would that work out to at an iPhone 326dpi? If my math is right that works out to ~3.93" a perfectly feasible iPhone screen size. This could have a really big benefit: it isn't introducing a new resolution but rather syncing them. Resulting in every piece of software made transition to the iPad that much easier. The form factor doesn't change that badly either. In terms of scaling the display ratio there is only 1/5" increase in width (that is, a 3:2 resolution would be 704x1024, bumping that to 768 is an additional 64 pixels, or 0.2" at 326dpi) I'm still skeptical that Apple will do this, but it might actually have a positive impact on App Store apps. That's physically 11% wider and 7% taller.
