Personally, I'm a minimalist who avoids buying anything that's going to take up space. I used to have shelves and shelves of books at my last place, but I ditched most of them when I moved. With 8 GB of memory, a kindle can hold more books than any man could read in a lifetime, and it weighs only a couple ounces. I carry mine with me everywhere.
My one worry with the kindle is that by putting your stuff on an electronic device that's linked to Amazon's network, you're giving them the ability to wipe your library if they decide they don't like you or what you're reading. It already happened with Orwell's 1984; there was a dispute between publishers and instead of just taking it off their site, Amazon took the book off of everybody's kindle. So I have a Kindle that's not linked up to anything, and when I download something I strip off the DRM on the computer right away.
