A Commonplace Blog (and several other sites) ponder the future of printed books.  Be sure to follow the links as well.

"Every reader has books that are special to him. Randall Jarrell used to say that he owned several copies of Christina Stead’s Man Who Loved Children (1940), because he so loved the novel that he pressed it upon friends (and friends never return books). Books to be used up and discarded—bestselling fiction, self-improvement guides, popular biographies, books on current affairs—belong nowhere else but on the Kindle. There is, however, another class of books altogether.

'No book is really worth reading at the age of ten which is not equally (and far more often) worth reading at the age of fifty,' C. S. Lewis said. And that brings me to my second reason for doubting the final disappearance of the 'physical book.' Namely, children don’t learn to read on the Kindle, but from the pages that they turn excitedly with their parents."

I know a number of people who love their Kindle; I have tried to read ebooks and so far the format hasn't worked for me.  Long live the stack.
