Apple loves thin products. The iPad 2 is now 33% thinner than the original!! YAY!!
But realize, somethings gotta give. Sure Apple claims they were able to keep the same 10 hr battery life.. but what if they had kept it the same size. Maybe they use a bigger battery to increase bat life to 12 hours. and also by saving money on slightly bigger parts they would have added a 5mp camera and hd facetime cam on the front. Maybe they also would have been able to make a 128gb model or add an SD slot... but instead they made it a few mm thinner.. Was it thin enough already? is it thin enough now? Would you like apple to continue to decrease the size on each revision as long as they are able to keep decent specs?
