Looks like we got ours on the same day!
Too bad about your screen issues, though. Huh, mine is actually from the same batch (503?) as yours, but the screen is almost perfect on mine.. There's a small pink area on the upper part near the edge of the screen, but I didn't even notice it at first. I only noticed it last night when I turned the light down a bit to read in bed. I was actually wondering if it is was the screen or just my eyes.
