Good to see some bundling. I've said for ages, if Amazon, for example, offered the hardcover of a book, plus an ebook version for another dollar or two, I wouldn't buy books anywhere else.
In fact, I was waiting for this kind of thing to happen before buying an e-reader (because I hate DRM).
I still love the idea. I'd even put up with DRM on the ebook if we got a real hardcover that we could loan out / have as a backup / etc.
