I can see the appeal of a Kindle, but when I find a book I love, I want it in hard copy form. To keep. Forever. I have several bookcases filled with keeper books (I don't dare count how many there are, but certainly more than 1500), books that I occasionally pick up to re-read, and some that get re-read regularly. (I'm a voracious reader, I will probably read at least 20-25 books a month, and that's a lot less than I used to read).
The Kindle wasn't meant for storage, I think it was meant for the purpose Orangeskittles alluded to - books for a casual read. The latest popular chick-lit or vampire book. Books you will read once and never read again. As someone who has probably twenty-five or thirty books in the TBR (to be read) pile, books I know will be one-time reads, I can see where the Kindle would make that a lot easier. But I still want the feel of a book in my hands, the ability to turn pages, and if something on, say, page 87 reminds me of something earlier in the book, I can quickly flip back to where I remembered reading that in the book. That's a physical thing you don't get with the Kindle. (I know you can scroll back, but I mean the physical feel of where that paragraph you're looking for is in the book. Like, it was right near the beginning, on a left-hand page, a page with a lot of dialog and no expository paragraphs. It's a lot harder to do that kind of search with a Kindle).
I think you also lose a certain sense of the pace of a book with the Kindle. With a hardcopy book you can see that you are nearing the end of the story, and that the climactic scene you are reading will be THE climactic scene in the book, not just another twist. You don't get that with the Kindle and frankly I think you lose some of the reading experience that way.
So...it has it's uses, but I'll stick with hardcopy books for now.
