As I stated in my previous installment, the big (really big) element of the iPhone is the screen.  

The large screen signifies the triumph of software design over hardware.  Gone will be the days of just programming a couple of softkeys.  

The iPhone subjugates the traditional phone functions to software display.  This design methodology requires more memory, a fast processor and lots of pixels to light on that display.  These elements all equal power consumption!  When combined with music, video, wifi and the occasional phone call, the stated power reserves seem aggressive.    

Similar to Rocket scientists who debate the use of weight capacity on a launch vehicle, the engineers at Apple must have had long debates on the allocation of power reserves to the various functions.  

Prediction: If the iPhone cannot last at least 24 hours with normal use – it will fail.  Expect extra-capacity batteries to be part of the iPhone, very soon.

The exciting and long-anticipated:
