I too have ordered (and am currently waiting on UPS to deliver) a black iPhone 5 and I couldn't give a damn about this.
Sorry but I recognise I am buying a device that will be carried around. No matter how good my intentions at some point it will end up in a pocket with keys, it will probably get dropped, it will inevitably get scratched. But it is a mobile device and therefore I accept that such things will inevitably happen. It has happened to every phone I've ever owned since 1998, it's happened to every mp3 player, every tablet and every laptop. It cannot be avoided and I buy a device to use, not to stare at worrying that it is no longer perfect in every way. Now if it arrives and it doesn't work, or if the home button drops out after a week THEN I will be complaining to Apple.
Oh and I really really hope that idiot who scratched up a demo unit and proudly posted pictures is identified and done for criminal damage.
It doesn't bother you that it's seemingly MUCH more sensitive to be scratched or visually damaged than the prior phone?
