It's an interesting phenomenon. Now that I have my Kindle, I find I can "parallel read" instead of sequentially reading. It's really easy to flip between several books, and the Kindle keeps track of what percentage I have completed of each book.

I'm finding that the Kindle might not be so good with technical books -- why, I don't know. But for fiction and "light" books it's great. I wished I had read Tolstoy many years ago. That guy can really write!
