I've got a perfectly good retina screen, and I looked at all the screens in my local apple store, and they are all good. Thus all Retina screens are fine, and any defects must be a minor problem. Alternatively I could realise that my local store make up a tiny % of the global market and I can't make generalisations without a more substantial sample. I get you aren't happy you got a bad screen. But the sky isn't falling.
