I love the feel and the smell of books - in fact, just walking into a library or bookstore and smelling the familiar scent of old books makes me happy.
Paper books of course! There is no better feeling than that of touching those pages, especially when the book is old and has that yellowish color. And that smell, only a book can offer you, most definitely not an e-book. Also, I love how they take half the space in my room, my own personal library ! No, nothing like a good paper book ..
