Amazon's graphite Kindle DX now shipping

Amazon promised that its new, Pearl display-equipped graphite Kindle DX would start shipping today and, as a helpful tipster informs us, the first shipping notices are now indeed going out. What's more, unlike some past Kindle debuts, the e-reader is also still listed as in stock, so it looks like you're not out of luck if you didn't get your pre-order in. Of course, it's not clear if that's due to increased supply or reduced demand -- although, at $379, we'd have to guess it's moving a bit slower than the regular $189 Kindle.
