I absolutely love physical books. I can't resist buying books. But I'd also love to have something like the Kindle, so I don't have to carry all the books around. The problem I have is that, as you said, with an Amazon e-book you get less functionality than with a book. Smaller choice, restrictions on purchase you can't have with a real book, and the ability for them to just disappear. It's like the whole mp3 thing, trying to restrict their use with rediculous DRM and TOS, but eventually they'll figure out that people will still pay, and in higher numbers, if you make them easier to use and distribute.
