I couldn't find anything on this so far so I'm starting a thread. I just purchased my first iPad (new iPad 16gb) 4 days ago and noticed there was this square area in the center of my screen that was resistant to fingerprints and grease. I could run my finger down it and feel a difference too. The rest of the screen would get horribly gunked up with fingerprint grease. I have a 4S so I know how the Oleophobic Coatings are supposed to act. I concluded my iPad had a coating issue and only that little area was Oleophobic Coated. Took it to the apple store and while wiping it down it was very noticeable. They kindly and easily replaced it. My replacement has the same problem, just in a different area. I now have steaks of uncoated area on the top right of the screen. It's going back to the genius bar for replacement later today. Heads up, check out your displays because THIS IS NOT NORMAL and apple will replace it under warranty/applecare.
