Everyone seems to rush to reply to say how flaring is normal. I don't think this is in the news because it's flaring, it's because it's drastically showing purple flaring.
I've had every iPhone version since the first, including the latest, as well as a Canon SLR. While taking shots that had sun rays coming down always had a typical white flare, only in the iPhone 5 have I experienced the "purple flare" and have it be so noticeable.
Just like with the scratching, every iPhone has been susceptible to scratching, however only the iPhone 5 has been so easily scratched on the edges. Within the first two days there were cheaps and scratches on the sides. Yet, I have old versions such as the iPhone 4 that have never had a case and still has no noticeable scratches. Overall, I think the iPhone 5 is the most durable in the sense if you drop it, it is most likely not to crack the screen and of course is the lightest. But it does scratch incredible easy and that is what customers are complaining about. If apple made a iPhone out of paper and people all of the sudden complained that it gets destroyed with even a drop of water, Apple and commenters would say well of course water drops will destroy paper. But what customers are saying is, the iPhone shouldn't have been made out of paper, or in this case a material that scratches so easily. Or they should have made the black version, black on the front (so the screen blends in) but silver on the sides and back (like the white model) since then the scratches wouldn't show through as noticeably.
So please commenters don't be so quick to mark all customers as dumb, and listen to what they are actually complaining about.
Easy marks is a new issue in the iPhone 5 (compared to old iPhones), noticeable purple flare in photos is a new issue in the iPhone 5 (compared to old iPhones), Maps are notcieably less accurate in iOS 6 (because of the new data set).
