I'd love to see Apple piss away 18 months and another refresh on making the screen size .2 inches larger. Ever hold a Google Nexus S? 4" is exactly what the iPhone 5 is going to be, Apple wouldn't waste their time any other way. Simple as that.
Why do people think that the iPhone needs to surpass or be like a Google phone?
Apple focuses on minimalism and functionality, so I don't see them trying to phisically copy android/google phones.
