Kindle DX
The Kindle DX, which has nearly a 10-inch digital paper display, is designed for viewing professional documents, textbooks, and other content where a large screen is desirable. Amazon also sells the Kindle, which has a six-inch screen that’s best-suited for reading e-books.
The Kindle DX has a text-to-speech feature to make content accessible to the visually impaired. However, the device does not include a similar function for the menu and navigational controls, making it impossible for blind students to find content or access the device’s other functions.
On a sidenote, Forrester Research estimates 3 million e-book readers by various manufacturers were sold in 2009 in the United States and expects sales this year to reach 10 million units.
