Playaway

I love to listen to audiobooks while I travel but I'm not always organized enough to put them onto my iPod before I leave.  These little Playaways are audiobooks housed in their own little players.  One (replaceable) AAA battery gets you through a 12 hour book.  The players come with their own set of headphones that plug into a standard jack (in case you want to use speakers, or your own headphones).  Playaway doesn't consider its players disposable; they encourage users to pass them along, just like a good book. Each book costs around $35 (prices vary depending on the book).
