From Wikipedia:

Amazon Kindle is a software and hardware platform developed by Amazon.com (subsidiary Lab126) for the rendering and displaying of e-books and other digital media.[1] Four hardware devices, known as "Kindle", "Kindle 2", a third generation device simply called the "Kindle", and "Kindle DX" support this platform. However, most reviewers, customers and press companies refer to this latest generation Kindle as the "Kindle 3".[2][3][4][5][6] Kindle software applications exist for Microsoft Windows, iOS, BlackBerry, Mac OS X and Android[7]. Amazon's first hardware device, the Kindle First Generation, was released only in the United States on November 19, 2007. The latest hardware device, the 3rd generation Kindle with 3G support for use in 100 countries and territories, was announced on July 28, 2010.[8]
Since the Kindle is still relatively new, and I just got one, I decided to put together a small site with information and resources as I founded. Also, since I already have two books listed for sale in the Kindle Store, I can provide downloads to the free editions of each book.

Where do I get books?
