I thought I would hate the kindle both for it's form factor and because I have a sort of photographic memory for page layouts when recalling information in text books. Since I don't read textbooks often anymore--most things are now searchable on the internet, what I found was the convenience of the kindle in being able to take a lot of books on travel, even pick them up at the airport, and also to make the fonts larger are killer reasons it's better than print. I personally use it to the exclusion of books for all new books. I still buy used books because the price is better.
What kills me about the kindle is two things. One is when I read great book the first thing I want to do is give it to a friend. And you can't. The second thing is you can't put it on your trophy shelf. I like looking at the books I've loved on my shelf as they recall bits of the story I liked at a glance. It tells others about me in a way I want to tell, and it's lets you pick one out and give it to a friend.
So I love books and hate the kindle, except that it's a far better tool than a book. It's just that books are more than tools, they have identities and you want to share them.
