Bezos just stepped off the stage after announcing that Amazon would drop the Kindle DX this summer for $489 - about $150 more than the smaller Kindle 2 released just a few months ago. I watched the live blog and left, on the whole, disappointed.
I love e-readers and want to see them succeed. Same with newspapers, so I think the NYT, WaPo, and Boston Globe subscription options are great, particularly with the larger screen. Gizmodo noted, and I agree, that this needs WSJ to become a serious player in the newspaper market.
There are two downsides: A lot of people just shelled out for the Kindle 2. Given the price and popularity of Kindle 1, I think a lot of people would have just waited it out for Kindle DX had they known it was coming so soon. Second, fine, so there is a bigger screen and PDF support, but to be a business tool this needs to permit annotation. iRex offers a touchscreen version of the machine for just $600. You can take notes directly on the PDF docs and transfer them back to your machine. You have "Whispernet," but they will really permit us to go paperless.
