Where does iBooks Author Play in the K-12 Landscape?

With all the focus over the past few weeks around Apple starting to sell textbooks via their iBooks 2 platform for the iPad, I think the most important part of their announcement was overlooked. 

The iBooks Author tool that provides users the ability to create and publish their own multi-touch textbooks is a bigger game changer.  Many school districts (like my own) write their own curriculum through a process with teachers and other leaders, and the ability to create these interactive and engaging textbooks that best meet a specific district's needs are of huge value. 

The iBooks Author tool allows the creator to insert text, graphics, videos, and more to create a customized learning tool that flows with their curriculum and meets the needs of an engaged learner.  These media rich, interactive texts provide students with the cutting edge learning tools they have been asking us for. 

I have spoke to colleagues who believe this first pass at the Author tool isn't as intuitive it could be for the average user, and I have complete faith (in true Apple style) they will streamline their product in a next release that will make the creation and publishing more intuitive.

What are your thoughts on the iBooks Author tool?  Do you believe it has the potential to be a disruptive tool in K-12?  Why or why not?
