You do realise Apple already uses the Exmor R sensor in the 4s, Its been proven its the same sensor. Apple dont have to call it Exmor R though. (thats sony's marketing wank)

Sony would make big bucks licensing their technology to apple. Sony should take some software hints from Apple in regards to the camera algorithms. Day to day shots the iphone smashes the arc.

Before you all whine at me I have an ARC S and prefer android.
