As most people think, iPhone 5s has non-thing surprised, expected for Touch ID (Fingerprint identity sensor built into the Home button) and A7 chip with 64-bit architecture (http://www.apple.com/iphone-5s/specs/).
Why I need 64-bit chip be equipped in my smartphone? To help consume the battery? Finally, I agree that 64-bit chip with 64-bit OS are both necessities for smartphones. As the camera spec. becomes higher, 20 Mega pixel will become basic spec. soon. When I used smartphone as the car recorder, the result is:
32-bit smartphone OS can not record video more than 4GB!
With 12 Mega pixel camera, the recorded length is about 32 minutes, though my smartphone is equipped with 64GB micro SD. Obviously, 64-bit chip OS and hardware will become the main stream in the smartphone market next year. The main reason is "high-resolution camera specification".
