I wonder if you can have a favorite e-book the same way you can have a favorite physical book? My favorite books I read multiple times, they have become worse for wear, I know every wrinkle I made while reading it, and, while reading it, it just feels right in my hands. I don't have that with e-books. Yes, the content is the same, but I am less able to form an attachment to a virtual copy than I am to a physical copy. Somehow, the holistic experience of reading a physical book versus reading an e-book on a e-book reader is different, although the actual content in both manifestations is the same. Maybe I am old-fashioned, but books and series I care about more, I still get physical copies. For my light reading, however, I'm fine with e-books.
