Summary: While its $110 less than the original price, the $379 Kindle DX still doesn't address the needs of its core education audience; the limited access to notes, inability to create or export notes on sideloaded documents, and mediocre typing experience make it hard to recommend on that front. It's a good choice for consumers who enjoy books and devour magazine and newspaper content, but may be overkill for those who stick to mainstream bestsellers.
Summary: The Kindle DX's hardware, like the Kindle 2, is a welcome update, and its larger screen, built-in accelerometer, and added storage space all sweeten the deal. However, its price of $489 is hard to swallow. Those seeking an e-book reader that can fit into a purse or small bag would do best to save $200 and go with Amazon's Kindle 2. But those looking for a larger display and larger images--and don't mind the extra weight--would be well served with the Kindle DX.
Summary: This is the larger version of the Kindle (reviewed around six weeks ago) A lot of the features are the same and should you already have some Kindle books you can view them on either unit, the main advantage more words per page.
