Amazon this afternoon said that it would ship the Kindle DX on June 10th, shipping its largest e-book reader ahead of the promised summer schedule. Launched just last month, the e-paper device centers on a 9.7-inch, 1200x824 display large enough to be used for textbooks and for a larger view of newspapers and other common literature. It accordingly gets an accelerometer to auto-rotate documents for viewing in landscape while gaining native PDF support to read many free documents without needing them converted.

It continues to draw on free Sprint-provided 3G for downloading books, reading blogs and using the rough built-in web browser; USB provides local transfer. Storage is handled solely through 4GB of internal flash memory. Amazon hasn't changed the price of the Kindle DX since its debut and expects it to sell for $489. Those who pre-order the reader should receive their units first.
