I'll add to the spasm of shallow posts about Kindle in the geo blogosphere: the Kindle does nothing for me. I like paper books. I like the user interface and I like the freedom. Mark Pilgrim captures Amazon's evolving view on this freedom with a couple of quotes:
When someone buys a book, they are also buying the right to resell that book, to loan it out, or to even give it away if they want. Everyone understands this.
