Yeah, that's presumably the last time McGraw-Hill get to do any pre-release deals with Apple. It's not clear to me how that stunt is a net gain to them.
If e-readers are really going mainstream, McGraw-Hill will have a whole lot more to worry about than a sour relationship with Apple.
Currently they do everything in their power to devalue 2nd hand sales, such as pointlessly churning the edition every year or two or even integrating course notes and syllabus for a specific professor. Once they go to e-readers there will be no 2nd hand sales and they can stop wasting resources on pointless editing and profit skyrockets!
Until MIT OpenCourseWare puts them all out of business. Good riddance.
