Where can the iPhone evolve from here? Here's one idea - let me know if it's crazy. A display on the back of the iPhone. (Yes, everyone would need clear cases.) This doesn't have to be a big battery drain - E Ink would do. Used for photography and videography. Frame your pictures (make sure your whole family is in the shot) using the outlines shown on the back of the phone. Something I would use: a teleprompter. Shoot a video using the high-def rear camera, read the words on the back of the phone that are synchronized via your voice. When not taking photos or videos, it could be "always-on" with the time and the Apple logo. Thoughts?
