I just figured out the downside, though. Short of lending my reader, I can't share my books. I've always participated in that highest form of theft--book borrowing and lending. I dare say I could match the books on my shelves that belong to others against those of mine that have likewise wandered off. It's a bittersweet loss. I most love to share with a friend a book that I've loved, then to have it return--along with the opportunity to talk about it.
Now I find that when I recommend a book, someone will no doubt ask to borrow it when I'm finished, and I have to admit I only have the electronic copy. The phenomenon is not limited to reading, of course. Now that we all have such quick and easy access to iTunes, no one borrows CDs anymore. I can only imagine what will happen when the technology advances and my reader (and iPod) are obsolete. Will I have a gap in my shelves--books and music? As a woman who still listens to her record albums and revisits favorite old books, I certainly hope not.
