Are Book Covers a Thing of the Past?

I love books. How they feel, how they smell, and how they look. It's easy to think that digital books or ebooks (what do you call them?) spell the end of the tangible pleasure of a book. To some extent that's true, but where digital excels is visual, so why does the look of a book have to suffer? It doesn't. Cover art is very much alive. I'm happy to see it memorialized by some great blogs and Pinterest boards. What's your favorite book cover?
