Amazon announced that the Kindle DX will start shipping on June 10th. It costs 489$, and currently available for pre-order. The Amazon Kindle DX is a wireless e-book reader. It got a large (9.7", 1200x824, at 150 ppi with 16 shades of gray) E Ink display, and Amazon is not just aiming this for books - but also for newspapers (they already signed up the NY Times, Wall street journal, The New Yorker and Time magazine).
The DX weights 535 grams, and the size is 10.4" x 7.2" x 0.38". It's got 4GB of internal memory (around 3.3Gb of which are available to the user). The modem is a EVDO 1xRTT (Sprint 3G).
