In an interview with CNBC, McGraw-Hill's CEO confirms that their textbooks will be on the Apple Tablet and it will be an iPhone OS based machine. When asked about rumors that their textbooks will be on the Apple tablet, Terry McGraw responds (2m 50s):

"Yeah, Very exciting. Yes, they'll make their announcement tomorrow on this one. We have worked with Apple for quite a while. And the Tablet is going to be based on the iPhone operating system and so it will be transferable. So what you are going to be able to do now -- we have a consortium of e-books. And we have 95% of all our materials that are in e-book format on that one. So now with the tablet you're going to open up the higher education market, the professional market. The tablet is going to be just really terrific."
