I bought and returned 3 iPads during the first week after launch and took them back because of screen quality issues. They had the pink/green tint and some areas of the screen were darker than others. I got a full refund and decided to wait a bit before trying again. Well, on my way home from work tonight, I passed a Best Buy. Something made me stop and see what they had in stock. They had a black 64GB 4G in stock and I decided to try one more. I'm happy to say that this one is a keeper! The screen really good! It's a nice even white screen with no trace of color shift or uniformity issues. I'm very impressed. For those that are having issues with the screen, please be assured that there are indeed really good screens out there. Take it back and get another until you get a good one. They do exist!
