It's a generation thing isn't it?
The more senior among us who have the reading habbit will still want and enjoy the experience of a proper book, younger people who are growing up in the technological age will adapt to E Books and take them for granted in the way they do with mobiles, texting, e-mail and so on.
The clue will be those who - like me - send all their texts in long hand, correctly punctuated, are unlikely to want to read a book on a screen, but as with everything, the E-book will find its level.
