My final update...
I just returned by 4th ipad2. First 3 had light leakage, 4th had no leakage, but dead pixels.
Went into the store, and the 5th one had even more dead pixels. It was at this point the manager said, "Look, you have to expect these things to happen. Perhaps you need something like a computer."
HAHAHA... I never got upset, not once, during my mutliple trips to the apple store for this issue. But for this guy to tell me I should expect defects and live with it, or maybe my picky personality needs a computer (of which I have 2 macbook pros and a Lenovo) I lost it. After arguing with him, he went back and got one more (he also told me they had no more).
After 6, SIX ipad 2s, this one finally is right. No dead pixels, no light leakage. Ok, on 100% brightness, you can see it faintly, but I was worried about the abitlity to see it in a moderately lit room at 50%. This one was a-ok.
I have to say after all this, Apple has really left a bad taste in my mouth. I'll probably fork over a ton of cash for the latest and greatest, but I'll be sure to not be an early adopter next time.
