My #1 concern with the new iPhone isn't the $10 boost in monthly data expense... but rather the hardware. One of my favorite parts of my old iPhone is that how incredibly durable it is. I've been carrying it in my pocket and throwing it on my desk now for about 10 months, and it has hardly a scratch on it. Has anyone found any information on the net on the durability of the new black/white plastic back of the iPhone 2.0? I realize that they aren't even available, but are there any guesses from educated individuals or maybe people who were at the show who got to see it and can guess as to its durability? Thanks!
