I could see a use of an E-book for my academic studies. Having all my reference books and journal articles in one "place" where I can quickly search between them would be valuable when I am writing my papers or doing research in a library.
But for my recreational reading it has to be books all the way. I love the library I have in my house. I have books there from the early 1800's and up. The smell and texture of books can't be replicated in bits and pixels.
Books have been faithful friends of mine for many years. I can't see abandoning them for a computer screen.
