Similar features to the regular Kindle but it boasts a 9.7″ diagonal e-ink screen. This new screen is capable of the same 16 shades of gray for clear text and sharp images as well. The form factor is larger in all dimensions as well; 0.02″ thicker, 2.4″ taller and 1.9″ wider. Due to the size increase Amazon has been able to beef-up the storage too as the DX can hold 3,500 books (2,000 more). Other neat enhancements to the Kindle DX is the ability to rotate the dislpay and a native PDF reader that is builtin vs. the internal conversion tool the standard Kindle uses. All in all the DX is a cool piece of tech but I really don’t think there was a market for a DX at this point in time. The Kindle DX is selling for $489 and can only be bought at Amazon.com.
