Amazon Kindle DX

The Kindle DX from Amazon is the most recent addition to Amazon's popular line of eBook Reader devices. Introduced in May 2009, the Kindle DX is the largest Kindle available with a screen size of 9.7". Most of the technology in the Kindle DX is found in the previous Kindle 2 with the main differences coming in the size of the display, and the size of the internal memory clocking in at 4GB (3.3GB usable). Other differences include native PDF support (other Kindles require conversion) and auto-rotation from portrait to landscape. The Kindle DX retains the same WhisperNet wireless technology as the Kindle 2 offering free wireless access for book downloads.

WhisperNet - One of the biggest selling points of the Kindle is the product's stand-alone nature. Since it has a 3G wireless receiver built-in, you can browse the book store, download and purchase books and download other content such as blogs and websites without ever connecting it to your computer. For a price you can add e-mail support which lets you e-mail content to your Kindle where it'll be automatically downloaded over the wireless connection. However, the WhisperNet technology works only in the United States, if you take the Kindle abroad the wireless functions are useless.

Automatic Backup - Amazon stores and logs all the books you've purchased from their online store, meaning you can redownload any books for free. Furthermore, Amazon's online services keep track of your bookmarks, annotations, and last page read.

Text Books and Newspapers - Amazon has established partnerships with leading textbook and newspaper publishers to offer digital versions of their publications. Newspapers may be offered at a reduced price with a long-term subscription. Prices for textbooks are still unknown.
