Well, I looked at the data, particularly in the U.S. on a weekly basis, after Amazon launched the Kindle Fire. And I wouldn't, in my view, there wasn't an obvious effect on the numbers plus or minus. The theory that you've got, I have heard clearly from some customers that, that occurred, that they went in thinking that they would buy that, they'd look at it and decided to buy an iPad. Whether that's happening on a very, very large basis, I don't know. Again, my own view is looking at our data in the U.S., there was no obvious change in the data, for what it's worth. That's how I see it. There is cannibalization clearly of the Mac by the iPad, but we continue to believe there is much more cannibalization of Windows PCs by the iPad and there's many more of them to cannibalize. And so we love that trend. We think it's great for us. The thing that is very different about the iPad is you can see it beginning to appear virtually everywhere. The enterprise has adopted it in a very large percent of the Fortune 500, as Peter talked about earlier. That number is also quite large when you look at the Global 500. In education, in K-12, we sold twice the number of iPads as we did Macs. And generally speaking, education adopts new technologies fairly slowly, so that's somewhat surprising. And of course, the consumer is -- has moved in a huge way to iPad. And so it's winning market by market, by market. I think that consumers that go in and look at it and think about the ecosystem and the huge advantages and the overall customer experience, I think we will win a fair number of those. And I think you can see that in the results. And so we couldn't be happier with doing over 15 million. And I think it's remarkable that we sold over 55 million iPads, and we've only been in the business April of 2011, I think, when we shipped the first one -- or 2010, excuse me.
Mark A Moskowitz - JP Morgan Chase & Co, Research Division: And then the other question I have is given your customer data, are you seeing any sort of phenomena now where, because of the accelerated refresh cycles, the widened gap in terms of what Apple has given to the customer base versus the competition's meager efforts, if you will? Are you seeing accelerated refresh rates within your customer base in terms of someone who buys an iPhone, maybe they're buying it quicker or maybe they're also buying now a MacBook Air or an iPad, do you see an accelerated refresh rate or a halo effect?
