Ebooks are obviously superior technology, however the technology is of more benefit to the publisher and distributor than the reader.

In fact, an Ebook requires a particular device and battery charge; it cannot be readily shared unless you want to give away or lend your device. You cannot easily annotate or draw a diagram next to a description. There isn't yet a satisfactory electronic equivalent to the experience of flicking through a book.

IMHO borrowing another student's well thumbed and annotated textbook will often be more useful than downloading my own pristine copy.
