Now, my home has no shelves full of books. All my (dead tree) books are in storage and I just have a kindle.
I still read as much as always, but I feel as if a certain degree of intellectualism is lost. No longer can someone look at my shelves and say "oh, I loved this book" and spark a nice literary discussion.
I should add, however, I am probably one of the few regular users of goodreads.com, though it is hardly a replacement (and I've only got one or two friends).
