I'd be annoyed if my expensive "object of desire" (whatever it might be) was nicked or blemished out of the box. But truthfully, when I saw the keynote introducing the iP5, I thought, "Aluminum? This will be a problem." Aluminum works pretty well for a laptop, but a phone? Who in their right mind would make a phone, meant to be stowed in your pocket or purse, from highly machined and polished aluminum? It's crazy. Even my Apple Remote (cast, machined, and anodized Aluminum) got beat up pretty quickly.
The phone looks nice and I love the internal and software improvements, but I think almost anyone would prefer something a little heavier or thicker that's designed to hold it's looks for more than a day. Stainless is th obvious choice in my mind. Apple designers always seem to forget that change for the sake of change is neither good design nor innovation. This is a classic Apple design mistake which they make every few years. Call it "Apple Hockey Puck Mouse Syndrome." (Actually, in that case it was Steve who insisted on the ridiculously stupid design of the "Hockey Puck Mouse.")
I predict machined and polished aluminum will not be a lasting trend for Apple mobile devices.
