Apple likes to control when it releases information to the public. That's why it doesn't present at trade shows anymore, but schedules its own events on its own schedule.

There's just one catch: As a public company, Apple is obligated to release quarterly earnings reports, as it did Monday. And its presence in the financial sector means it needs to explain its business to analysts, at least a little bit. This is why we get a little piece of delight every three months: A phone call featuring CEO Tim Cook and CFO Luca Maestri talking to a small group of Wall Street analysts.

Given Apple's tendency to keep its executives on message, this call could easily be a snooze. But it's not, I suspect because it has become an effective tool for Apple to explain parts of its business--and yes, there's some spin involved too--to the financial community. Every analyst call has a few tantalizing tidbits, and Monday's was no exception. For me, the two highlight topics were China and iPad.

Apple and China: BFFs

There was a time when people made the case that Apple absolutely couldn't make it in China. Its products were too expensive, it couldn't compete with Chinese tech companies who better understood the local landscape... that sort of thing.

Welp. Apple's year-over-year growth in China has outpaced any other region for eight of the past ten quarters, and has exploded in the first six months of this year, with year-over-year growth of nearly 75 percent. This past quarter, Apple had record revenues in China, with 70 percent year-over-year iPhone growth.

The App Store has doubled in China in the past year, and Chinese developers have made $2.5 billion in revenue in the past year from the App Store. Apple's online store revenue has tripled in the last year.

And it's not just the iPhone that's doing well for Apple in China: Mac sales were up 31 percent and the iPad had its best quarter ever there, both in markets that are projected to be down overall. "Once again, bucking the tide," as Cook said. "Everything you look at in China was extremely good."

China's a vitally important market, and Apple is giving it the attention it deserves. Sometimes it seems like using the word country to describe China does us all a disservice, because China's population is enormous. It's nearly twice that of all of Europe. It's more than four times the population of the United States.

And within that population is a rapidly growing middle class that Apple is targeting--and finding great success. As Cook said Monday:

I've never seen as many people coming into the middle class as they are in China. That's where the bulk of our sales are going.

If you look at [Brazil, Russia, India, and China] within the emerging markets, [those] countries were up 64 percent year over year. And so... it's clear to me that [growth] has to be coming from the middle class. Because the upper income earners, there's only so many of those, and you can't grow those kind of numbers without getting significantly into the middle class. And so that I think that's where we are, and I hope we're also beyond the middle class, but I don't have the data to suggest that's the case or not the case. But it's clear to me that the middle class statement is true.

It's hard to imagine the scale of serving a market double the size of Europe or four times the size of the United States--even if the middle class in that market is a smaller percentage of the whole--but it's vitally important for Apple's growth. Apple has been focusing on China for the past few years (including several Chinese-specific features in both iOS and OS X), and it seems to be paying off.

Tim's still an iPad believer

Then there's the iPad. I love mine, you might love yours, but when we talk about raw numbers, things are... problematic. After an initial flurry of sales, iPad growth has come to a stop. Year-over-year iPad sales have been down for five consecutive quarters.

To be sure, the iPad is still a valuable business for Apple. Last quarter it represented ten percent of Apple's revenues, roughly the same as the Mac. But the growth has vanished, which troubles growth-focused financial types. Tim Cook, on the other hand, says he's not worried:

When you look at the underlying data, it makes you feel a lot better than the sales do. Things like first-time buyer rates, the latest numbers from the U.S. are like around 40 percent, and when you look at China they're almost 70 percent. These numbers are not numbers you would get if the market were saturated... We also see usage numbers that are off the charts, so far above competition, it's not even in the same planet. And we see customer satisfaction at or near 100 percent. So these kind of numbers, along with intent-to-buy numbers, everything looks fantastic...

I believe the iPad is an extremely good business over the long term. When precisely it begins to grow again I wouldn't want to predict, but I strongly believe that it will.

This whole section of Cook's remarks reminded me of something from the world of sports statistics. There are two ways to look at a baseball player's stats: There are the raw numbers, like hits and runs (or for pitchers, ERA or hits allowed). And then there are the peripheral stats, more esoteric numbers that might not reflect performance on the field, but are a good predictor for what the player will do next. A player who isn't hitting or pitching well, but who has good peripherals, is likely to bounce back--they've just been unlucky.

What Cook is saying is that the iPad's peripheral stats look good. There are lots of first-time iPad buyers, a good sign that the overall iPad user base is growing. The usage numbers show that the iPad is used much more than Android tablets. And Cook's favorite statistic, customer satisfaction, indicates that people love their iPads--they're just not buying a new one every year.

Then there's the other issue with the iPad, which is that Apple also makes a couple of iPhones that are much closer to the iPad in size than previous generations, as well as Mac laptops that keep getting smaller and thinner. On Monday Cook agreed that those product lines are eating away at some iPad sales, but he thinks that's okay:

Have we had cannibalization? The answer is yes. We're clearly seeing cannibalization from iPhone and, on the other side, from the Mac. Of course, as I've said before, we've never worried about that. It is what it is. That will play out. And at some point, it will stabilize. I'm not sure precisely when, but I'm pretty confident that it will.

It would be easy to suggest that Cook's statement about not knowing when the iPad will rebound, but knowing that it will--along with hints about "continued investments in our product pipeline which we're doing, that we've already had planned and have had planned for some time"--is him just kicking the can down the road.

But as Cook has said on previous calls, it seems more likely that the iPad story is one of an initial rush of enthusiasm, followed by a slower trickle of new users. Many people replace their iPhones every couple of years; iPads appear to be on a much longer replacement cycle, more akin to a Mac or PC. Just yesterday I heard from numerous iPad users talking about how they're still using the iPad 2.

At some point, those people will finally buy a new iPad--assuming that those 100 percent satisfaction scores are accurate. The bear argument for the iPad is that a lot of current iPad owners just won't bother buying a new model, preferring to use their iPhones and/or Macs to do those jobs. As Cook said, that's bad for the iPad but it's still good for Apple.

Me, I'm bullish on the iPad. No, it's not going to ever be the iPhone. But a business the size of the Mac, growing faster than the tablet market as a whole, is still a pretty good business to be in. The iPad may not be the product for everybody--at least, not today--but it doesn't need to be. It just needs to be great at what it does, and I think it is.
