Apple on the other hand, seems to have bigger problems. Between the retina display devices and the non-retina display devices, to get an application truly compatible across all of Apple’s devices, you need to include 4 different UIs, which includes different resolution textures, graphics, and layouts. While the retina display iPhones have the same resolution as the non-retina display iPads, they can’t utilize the same layouts. While this concept makes no sense to me, it’s obvious that Apple thinks different.
For non-static content, such as OpenGL rendered objects, a developer needs to render at retina display density to support those devices (even if it isn’t necessary, in which case the resulting render gets scaled back, causing it to lose detail), or render at lower density, and have your renders look blocky on the retina display devices. Or double your code, one renderer for each device, and double your fun!
