I've been seeing this come up lately in discussions. Particularly from people who would want the 5.5" screen to run iPad apps. If that were the case, the 5.5" iPhone would be 4:3 instead of the 16:9 that the current iPhone has. I'm very slow when it comes to figuring out dimensions and mathematics so my question is what would we be missing if the phone got 4:3 instead of 16:9? The more and more I've thought about it, the more I like the idea of being able to use iPad designed apps on a bigger screen for an iPhone. I know that would cause some issues for app developers so that right there tells me that staying at 16:9 would be ideal since current apps could just be letterboxed for 16:9 until they get updated. But what else?
