Everyone gets excited every time Apple goes thinner than the previous model, but I'm curious if people really feel the tradeoff in features and power is worth it. With products as small as the iPhone then every millimeter of space can be used for something. For me, I'm not happy with the battery life or the cameras indoor/fast motion/low light performance so (IMO) I'd much rather get an iPhone with the "fat" 4S thickness if it means more space for better camera optics and another 2hrs of battery. But what about everyone else? Are you finding true benefits from a "thinner than the 4S" design or would you prefer to have more battery life/better optics/less heat/etc in a slightly thicker shell?
