Matt Drance has an interesting perspective on the iPhone 4 debacle:
Whether you are the CEO of the second largest corporation in the U.S. or a general in the U.S. military, it should be no surprise when the press reports what it sees and hears. If a media outlet reports garbage, then all things being equal, its reputation should pay a price. If it has information that it believes to be both material and credible to a relevant topic, it is not obligated to sugarcoat that information, but to report it.
Antennagate is news exactly because Apple has hit so many home runs—and, by the way, received countless glowing headlines to match. Apple should be nervous when this sort of thing isn't news: it would mean nobody cares anymore.
As I said earlier, I think the press conference was by and large a success; however, Apple will soon run out of goodwill if they continue to respond to criticism the way they did before Friday.
