Yeah, I was really pissed off when they told me they probably wouldn't even exchange it (much less return it), even though the screen was clearly showing the washed out/shimmering blacks.
I got mine at around 4:30pm Friday (about an hour after they got them), so we probably got them from the same batch.
If they still refuse to exchange it i'll probably try to contest it with American Express or something.
Kinda makes me wish i had gone with the 8gb. Maybe in a few days they'll change their stance.
