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 dunno, maybe it's in comparison to the basic chargers which used to come with the cheapest phones - they were just a transformer, a couple of diodes and a capacitor. No regulation, no filtering. I don't know if they're still around though...
