Kindle or iPhone: what do you use to access your favorite content?

Amazon’s announcement of their new Kindle 2 offered some interesting concepts in the publishing market, and is starting to reinvent the way we consume our books, newspapers, and magazines. By the same token, the iPhone has reinvented the way we listen to our music, connect with others, and use our mobile devices. However, the iPhone also does, to some extent, what the Kindle was built around, and that is reading books.
