Starting an eBay Business For Dummies on a Playaway audiobook?

I opened a box from my publisher the other day to find the latest iteration of one of my books, it's on a Playaway(?). I went to the website and checked it out:

"Playaway is the newest format of audio, combining a wide variety of content with an easy-to-use player all in one small unit. When you receive your Playaway, all you have to do is press play to start listening immediately – there is no need for a separate player, and it comes with earbuds and a battery to make it play.

Playaway is the most simple and immediate way to enjoy music and audiobooks. Its portability allows users to enjoy their favorite authors and titles on-the-go, whenever and wherever. "

Well son of a gun, sounds interesting, so I emailed the manufacturer for more info. They didn't respond. I guess I'm not a big enough name. Their site featured a trade-in program, which makes these audiobooks pretty green.

Amazon sells them too: Starting an E-Bay Business for Dummies (Playaway Adult Nonfiction) and it seems they have a co-author attached to it. After some studying (since I've never heard of the co-author) it seems the person listed "reads" the book. What the hey? I've checked him out - he's big in the voice over industry, so I guess that makes his reading my words equally important as my writing the book.
