"The new big-screen Kindle DX also has a larger 10.4 x 7.2 x
0.4-inch profile and weight (18.9 ounces), as well as a higher
price tag ($490) than the Kindle 2 electronic book (e-book), which
shipped in early March. By comparison, the Kindle 2 measures 8 x
5.3 x 0.36 inches, weighs 10 ounces, and costs $360.
"The Kindle DX also boosts flash storage from 1.4GB to 4GB, of
which 3.3GB is available for user storage. As a result, the device
can hold up to 3,500 books, periodicals, and documents, says
Amazon.
"Like the Kindle 2, the Kindle DX's screen offers the latest
E-ink gray-screen technology with 16 shades of gray. However, it
also provides the larger 9.7-inch size (up from six inches) and
higher 1200 x 824 resolution (compared to 600 x 800). It also adds
accelerometers to let the device auto-rotate like a smartphone,
automatically switching from portrait to landscape as the device is
turned."
