This is a phenomenal week to be covering the publishing industry. Tuesday, Apple released its quarterly earnings. Big surprise, another record-breaking quarter for the folks in Cupertino. A few billion here, a few billion there, blah, blah. How amazing is it that we're not really surprised by such overperformance in an otherwise still-troubling economic environment? Of great interest to me, the eReader guy, was the final iPad tally for the quarter ending June 26th: 3.27 million units worldwide. Still no good guidance on what the US split is, but no matter how you slice it, iPads are hot. (And, no, I still have not bought one, still holding out for iPad 2.0).

And if you follow the implications of that success, as many in the media have, Amazon should just concede the eReader business, pack up its cream-colored Kindle and go home, right? 

Wrong. And to prove it, Amazon made a point of announcing some news of its own, the day before Apple's results were public. Amazon flaunted its own success in selling both Kindle devices and eBooks. That's right, despite that iPad upstart, the Kindle is still flying off the shelves, selling more units each month than the month before it all through Q2, when the iPad challenger was supposedly pummeling it. And it's dominating the eBook business as well, selling as much as eight in ten of the eBooks of major bestsellers, seeing its eBook sales rate triple over last year. Oh, and Amazon indicated it sells 1.8 eBooks for every hardback book it sells. That's right, even though it discounts hardbacks to paperback prices for many bestsellers.
