Wait! Philip Elmer-DeWitt of Fortune says that Apple’s education event isn’t about “a GarageBand for e-books” at all:
MacInnis also mentioned GarageBand in our interview. But what he was describing was a sample iPad textbook, produced in-house and packed with pedological bells and whistles, that would serve as a reference design for textbook publishers, much in the way GarageBand for the iPad showed iOS developers what the new platform could do.
MacInnis does expect Apple to unveil new tools for creating iPad textbooks, along with a new content repository to make e-textbooks easily available to teachers. But the tools are not a “GarageBand for e-books.” And according to MacInnis, they’re designed to support the textbook industry, not to do an end-run around it.
