Amazon.com announced that the Kindle DX, its newly released large-format wireless digital reading device, will begin shipping on June 10. The Kindle DX is available for pre-order and Amazon says all orders are prioritized—first come, first served. Amazon launched the larger (9” x 7” screen) enhanced version of the Kindle 2 in early May along with deals to offer newspapers and college textbooks on the device. Amazon offers more than 290,000 titles for the device and the Kindle DX will sell for $489.
