Whoa, buddy, who shit in your cornflakes this morning?
The increased resolution works even when type is enlarged. Even old folks can tell that. My father is 78 and can easily appreciate the resolution difference between the iPad 2 and 3 (it's called having glasses that work). And yes, that increased resolution makes properly ripped movies look better too. Or do you somehow think that people in their 70s are too blind to appreciate the higher resolution there, too?
The camera is because while maybe the guy only says he wants to do a couple of things, it leaves the option open to him to use the camera. For someone so het up about eyesight issues, surely you already knew that the camera app also works as a magnifying glass, right?
But hey, go ahead and only answer the feature set part of the question rather than actually analyzing the problem. Maybe you could post like an patronizing twat while you're at it.
