Audiobooks on the Kindle

Kathy Schrock's Kaffeeklatsch: Amazon Kindle 2 Thoughts: "I chose a title, Bill Bryson's 'In a Sunburned Country', to use for determining the answer to this question. Bryson's print book is 352 pages in length. Audible's format-2 of his book is 46mb in file size, format-3 is 86mb, and format 4 is 172mb. That seems to indicate that, on the Kindle's 2GB storage drive, you could have forty-five format-2 Audible recordings, twenty-four format-3 recordings, or twelve format-4 recordings. (And of course, various numbers of the combination of the formats.)"
