I've actually been the sucker that buys multiple format/size books
In the past, the long long ago, before ebooks...I had bought hardcovers AND paperbacks of the same books. The paperbooks were just so darn convienant.
Now I'm having the same problem with ebooks, my paperback collection has started to shrink and my ebook collection grow. I still cant get over the not having the actual physical copy of the book for authors I like, or where I think they're pretty.
Ergo, I have just about every Weiss/Hickmann, Brooks, Koontz, and several others thrown all about my library and e-devices. I think it'd be a great feature to have and would probably buy a lot more hardcover books for myself if I had the option to get an ebook for free, or upgraded
Something like "complete my album" that itunes offers.
But then again, with Amazon's pricing right now books are already a steal.
I think Brandon Sanderson experimented with this when Warbreaker was released. I think he was offering an ebook thru Tor if you bought the hardcover. Some of our other author friends on this site have done similar things. You know who you are
