If the iPhone 5 is moving to a 16:9 aspect ratio and a smaller dock connector, that must certainly also mean that the next iPad will also be 16:9 and come with the smaller dock connector. Won't changing the iOS family to 16:9 screens mean more development specifically for 16:9, leaving current users with a rather unsatisfactory experience?
The iPhone 4/4S design already looks trendy and dated compared to the slick stuff we are seeing from HTC, Nokia and Samsung. If Apple sticks with the same design, and if even remotely close to what these leaks reveal, I will be selling my Apple stock and will not be purchasing an iPhone 5. In terms of industrial design, these prototypes just don't make sense.
