Same thing...
I love my iPad, and I use it all the time, even more then my MacBook Pro, but have been having this image retention issue, and IT'S DRIVING ME NUTS!! I would take it in to the Genuins Bar, but the last time I took one of my iDevices in for an LCD issue, they didn't believe me. I'm afraid the store is going to put me on a "Lier" list and won't listen to me anymore. I am a very loyal Apple customer, hell, my whole family is! Altogether, just in my immediate family, we have 7 iPhones (2 are mine), 5 MacBook Pros/MacBooks, 1 iMac, 2 iPads, 13 iPods (yes, 13!), and 5 AirPort Extremes. I'm definitely not a first time customer, and because I'm the "tech genius" in the family, I take everyone's Apple products, because I know how to describe the problem.
