I don't get the Kindle - I can see a use if you load it with reference manuals, so you don't have to haul them all around to worksites etc. (although a laptop serves the same purpose...), but for novels, etc. - seems like a very expensive solution to an imagined problem. My paperback books are cheap, I don't care if they get dirty or stolen or forgotten on an airplane, and when I'm done with them I can pass them to friends, or sell them, or donate them to the local library, or just put them on a shelf for a potential reread later in life.
The Kindle can break, get stolen, etc. It just seems like one more thing I'd have to take care of, and it's expensive to boot. And the DRM problems make it a non-starter as far as I'm concerned.
Besides, after reading a really crappy Stephen King book, you don't get the satisfaction of using the digital file as toilet paper...
