I think it's too early to say whether every panel vendor is delivering the exact same gamut spec'd panel to Apple. iFixit called theirs an LG. But who has ID'd a Sharp panel? How do we know what it looks like? What if the entire first batch is all LG? Or what if North America got LG panels and Europe got Sharps? And what of Samsung? We don't know if they signed on or not, and if they signed on, whether they've produced any yet or not.

Antennagate is a bad analogy. It was not a matter of preference or perception. It was an unintentionally flawed design. Apple doesn't publicly make amends for matters of preference or perception.
Depends on how you look at it. I used a iPhone 4 without a case for 2 years and never dropped a call. Neither did my wife. You come on to this site during any new product or software release and it's always the end of the world. Yet the same people keep buying the new stuff then complain again.
