One of the reasons I chose to start this class at this particular time was because the textbook was available as an eBook from Barnes & Noble for the Nook. If you prefer to use eBooks as well, or don't want to wait for an order to arrive, here is the link to the Nook Book edition at Barnes & Noble:

You don't have to have a Nook to read Nook Books. They have free applications available for your PC, iPhone, iPad, and Android. I'm reading my on a Motorola Xoom Android tablet and it's a great experience. As I read I can highlight the key points, which makes assignment #1 really easy to do when I review those highlights. Here is a link to the free Nook apps:

A few weeks ago, the book wasn't available as an eBook from Amazon, but I just checked and now it is. Here is a link to the page for the Kindle version:

The eBook is $9.99 from either store, which is much better than the $19.99 list price for the hardback book.
