"The iPhone 5 does not have a HD Screen" was one of the first criticisms I saw of the iPhone 5 - closely followed by the assertion that Android phones like the GS3 and One X do, but the iPhone 5 doesn't. I don't understand what this means? Can someone explain? I thought the iPhone 5 had a 16:9 aspect ratio with "retina" ppi? Is this not HD? In which case, what is? What is the downside to it not being HD? Clarification appreciated!
