You are absolutely correct.
The wear and tear on the iPhone 5 is going to be a HUGE issue, much bigger problem than the original antenna gate was. The iPhone 4/4S is FAR more resistant to wear and tear. Sure if dropped just right the 4/4S back will shatter, but it's replaceable, the iPhone 5 will dent and scratch and it is NOT replaceable. Not good.
Whoa didn't expect that to happen. I mean it's seriously a downgrade over durability to replace a stainless steel band with anodized Aluminum unibody. I don't see the miracle of it being lighter then. It's simply replaced by Aluminum, which is lighter but not as strong as stainless steel.
OMGit'ssolightandmagical ..
Well I'm pretty sure it's not Duralumin or something fancy, just pure cheap billet being machined and anodized.
Oh so much for Apple talking about [improved durability] on iPhone 5
