I'm sure people said this about the Macbook Air. I personally find value in having a less obtrusive object in my pockets and I look forward to the iPhone Air. I checked my own personal stats and I rarely use the other pro lenses on the camera system, and the battery life is the same as my existing pro. For me, there's nothing exciting to upgrade for except for having a better in-hand feel, which the Air offers.
