The thing that I wonder about to do with the screens is: if they make the screen bigger, what resolution would they use?
They'd either have to:
- keep the resolution the same, meaning it wouldn't be 'Retina' (326ppi) anymore
- Keep it at Retina levels, meaning we'd have an irregular new size and all apps would need to be resized
- Use some multiplier of the current levels (eg 1.5 the number of pixels), so that apps could be rescaled more easily, but this would mean cramming even more pixels into a small space
I can't see them creating a new size as all current apps would look odd on it, I don't think they'd keep the resolution the same, as the ppi would decrease, making for a worse screen overall, so would they have to use the third option?
