The 5 is already pretty damn thin. I have to imagine that we must be reaching a point of diminishing returns here soon. If we keep moving toward credit card thickness (but the same HxW), it doesn't get that much more portable and it just gets harder to hold. Hopefully the attention gets shifted to bezel death or battery life at that point. I mean, am I wrong - does anyone here even *care* about an even-thinner phone?
