TLDR (from PDF):

As this article demonstrates, print books are still the best suited to the optical, cognitive, and metacognitive requirements of the reading brain. While e-paper technology has been shown to be the optical equivalent of print on paper, e-readers still are lacking in the physicality that has been shown to be so important for comprehension. E-readers also lack the haptic qualities that readers enjoy about books, and seem only willing to give up only when convenience and portability are at a premium. In terms of metacognition, ereaders provide limited opportunities for text interaction, while virtual page turning has been demonstrated to discourage review of previously read material. Computer-read texts have all the limitations of e-readers without the superior optics of e-paper, and the added cognitive disadvantage of distractions from multitasking. Hyperlinks, once thought to streamline the learning process, have instead proven to interrupt the seamlessness of the reading process from perception to thought processing, and this is when they are passed over. If links are actually followed, the lack of textual linearity is sure to lead to confusion. When learning from a text is the objective of reading, printed books will remain the preferred format.
