So kids have to reboot their computers in order to read the textbook? Right, because that will definitely work... You've just blamed DRM and, in the preceding paragraph, fallen victim to the same fallacy that makes DRM look like a good idea: a computer is under the control of the user, any piece of software or content that seeks to control the computer will likely be broken and rejected. Also, what do the operating systems have to do with anything at all? Have you ever even used an ebook? I buy DRM-free books from O'Reilly all the time. But I would never buy a reference book in epub format because I like the ability to flip back and forth between many different sections of the book very quickly (if I have several sections marked I can literally flip to the section I want while picking up the book). Regardless of how good the ebook software becomes, I doubt it can achieve the simplicity of a paper book in this regard. I often use textbooks as reference books, so I feel similarly about textbooks. Maybe you, or others, don't use certain books in the same way I do. Maybe you do, but don't have the hang-ups that I have. Fine. But that doesn't mean that the solution to my (or others who feel as I do) problem is just better software. That's unbelievably arrogant.
