I'm not horribly old-fashioned in most respects, but I absolutely love tangible books.  My grandmother was a librarian, I worked in my town  library all of high school, and I'm the volunteer librarian at my town's Senior Center.  Libraries and book-books are in my genes and in my blood!  I have a half dozen library cards, I order discount books through Abebooks.com, and buy some at the Salvation Army store.
I tried reading a book on my cell phone and got maybe 2 chapters in before I hung it up. 
 
For all that, I only read my books before bed and on whatever beach I'm on.  And listen to them on CD in my car.
