The Kindle: Amazon's Wireless Reading Device may seem like an unlikely purchase from someone who listens to audio books. Listening to audio books is a great time saver. However, it is not possible to bookmark, take notes, or highlight material. During and after listening to books, particularly business books, I use them as reference material. The Kindle provides a compact, portable library of reference material. With a library of books on the device, the Kindle provides search for the entire library. For example, I may want to reference information on "accountability". The Kindle quickly provides access to readings on the topic from my library. In addition, the Kindle has highlighting, bookmarking, clippings and note taking features. And when books are not available in audio format, the Kindle is my preference when reading.
