Not only that Marco took some nice photographs on the show, he also wrote a nice afterthought on it:
With the wrong interviewer, this could’ve been a recitation of PR-friendly softball questions with perfectly designed, talking-point responses that would’ve gone nowhere and benefitted no one. But Apple PR doesn’t want that any more than the audience does. Or it could’ve been boring questions about hardware rumors that no Apple executive would ever answer. I’ve never seen another interviewer that didn’t waste time on these dead-ends that, in their wildest dreams, might answer questions relevant only for a few short months or years. But John Gruber is better than that, and we all know it, including Apple.
