McGraw-Hill CEO, has confirmed that Apple will be announcing a Tablet tomorrow, which will be iPhone OS Based. There is no denying this one. Straight from the man himself. Here's video to prove it.

"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 is 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."
