The latest Apple tablet rumor isn’t about the hardware specifications of the so-called iTablet; it’s about the notion that Apple has been having secret talks with newspaper and textbook publishers. The talk has sparked a new question: Might an Apple iTablet change publishing forever? Yes. Yes, it will. That’s the short answer. But there’s more to it, of course. Apple has been in talks with publishers to negotiate content for a “new device,” according to anonymous sources cited by gadget blog Gizmodo.
