Nothing will ever give me the same feeling as reading paperbacks or a hardcopy book. I don';t know how they read a book using kindle (of course I've tried it, but it took me 9 days to read the book, while I would have finished the book in a few hours if it would have been a paperback). What I miss the most in the ebooks, is that the rustling of the pages. As Amanda said, the if I can't feel the book in my hand I don't feel like I'm reading it. And of course like Harietta and Rook, what's the point of reading the book if you can;t smell the pages! lol
The stories we love best do live in us forever, so whether you come back by page or by big screen, Hogwarts will always be there to welcome you home.
