Yeah, my k800i from early 2006 still kicks my 3GS's ass in taking photos. If you're just going to ignore a blindingly obvious example of how Apple stagnates when there is not pressure, then I can't help you.
My partner and I went into London on a cloudless summer day and took the same pictures, Westminster Abbey, the soldiers on horses outside the palace in Whitehall, Nelson's Column, Big Ben, the lions in the fountains in Trafalgar Square, we then got our mutual friend a highly respected motorsport photographer who travels the world to photograph races to judge the images and give his opinion on what was the best camera and he overwhelmingly decided on the iPhone 4 images.
