Of course, "enhanced books," "vooks," etc. are ideal for tablets and nonstarters for eReaders such as Nook and Kindle, which are not designed to handle multimedia. But this fact is not a death knell for eReaders as a class of devices, especially as these become steadily cheaper, elegant, compact and efficient. I can easily see myself traveling with a tablet in my briefcase and an eReader in my breast pocket. I don't always want or need multimedia. Sometimes I just want to curl up with a good book, and to do so without digging out the tablet. The simple eReader e-Ink screens are MUCH easier on the eyes when it comes to extended reading.
Multimedia E-Books, Adorned With Video Extras - NYTimes.com: "Penguin Group released an 'amplified' version of a novel by Ken Follett last week. And on Thursday Simon & Schuster will come out with one of its own, an 'enhanced' e-book version of 'Nixonland' by Rick Perlstein. All of them go beyond the simple black-and-white e-book that digitally mirrors its ink-and-paper predecessor. The new multimedia books use video that is integrated with text, and they are best read — and watched — on an iPad, the tablet device that has created vast possibilities for book publishers."
