Hardware, Embedded Systems "Disassembling Apple's diminutive inch-cube iPhone charger reveals a technologically advanced flyback switching power supply that goes beyond the typical charger. It simply takes AC input (anything between 100 and 240 volts) and produce 5 watts of smooth 5 volt power, but the circuit to do this is surprisingly complex and innovative." Quite fascinating, although I'm not sure just how much the mentioned advantages really matter beyond bragging rights.

I agree you.
There's no hi-tech feature in this circuit at all... All of these are common electronic components in a common switching power supply design. Delivering 5VDC up to 5W is fairly easy to achieve. Otherwise compare my laptop's power supply that delivers 18V @ 6.5A (117W): it is not much bigger than the iPhone's charger (considering its high power features).

The only innovation I see is the fact of distributing components along the 3 dimensions instead of distributing them in 2 dimensions, as usual.
