Exactly! Kudos to you for bringing out such an excellent example.
I was going to comment that we weren't there to hear Shiller's response, nor are we certain as to the context of the question or any hidden motives to keep future plans quiet. I think Apple has shown itself willing to bluff in the face of questions and speculation from observers. The iPod video example above illustrates that perfectly.
I'm willing to bet there was a little tongue-in-cheek tone to Shiller's answer, an I'm-not-going-to-tell-you-the-truth-and-we-know-it sort of thing that maybe the reporter didn't catch.
His response seems a little evasive, just on the surface, and a tad off-base. Just offering the ability to run Windows doesn't automatically mean Apple must support it. If it's an elective feature, Apple can simply fend support calls off with a standard sort of "You'll have to call Microsoft" type of disclaimer. Providing that's made clear up-front, I see no problem with that, and MS should support Windows even on a Mac. What's the problem?
So I'm not sure I buy it. Apple is very definitely moving the in the direction of greater Windows compatibility and offering a Windows-in-OS X type of feature is a no-brainer.
We'll see, I guess, in a few weeks.
