On TWIT's Tech News today Mark Gurman was interviewed about his battery life article. In it he said Apple was having problems with the inductive charging time and that Apple had experimented with several types. He said Apple will probably have 2 types of charger 'pucks'. For the SS/Edition it will be the metal one shown on the Apple site. For the $350 Sport it will likely have a cheeper plastic back 'puck' that may not charge as fast. Of course if this is the case you could just buy the metal puck and have the same charger. Also there will probably be 3ed party available soon.
