Enderle got it wrong...
Via John Welch came a link to an outrageously wrong article on O'Reilly's MacDevCenter. Quote:
"Apple is really the only firm that doesn't use nondisclosure agreements and, as a result, they stood alone in this. (...)"
Anyone who owns an ADC account had to sign an NDA. Heck, all of WWDC except the keynote is under NDA. Now, the O'Reilly guys asked Enderle for his opinion, and he failed to research his claim, so they can pass the buck, but a real reporter would have gone and verified such an outrageous statement before just printing it.
I guess MacDevCenter is a blog without a personality, not a press site run by a tech company that focuses on tutorials and also delivers news...
