Mine arrived a few days ago direct from Shenzhen but unfortunately I have a noticeable change in screen temperature across the panel. Nearest the home button is noticeably yellow or warm compared to the top part which is a very cool white, almost bluish. I've booked an appointment at my nearest Genius Bar on Monday but they don't show any poverty packs (16gb wifi only lol) as in stock so even if they agree there's an issue I don't like my chances of an immediate in store swap. So I might have to wait, pay to upgrade or roll the dice on another unit direct from the orient. I'm thinking the former is safest as I don't want to be swapping again... Anyone else noticed a similar issue? I realise screen temp varies from panel to panel and having owned every model of ipad I can live with the variance if it's consistent but this is too annoying... I didn't want to believe apple skimped on the display but they do appear to be having a few issues with the new model including burn in :-( I do love the retina display though it really makes the mini!
