Bob, I did not see the demo done by Jeff Bezos of Amazon, but I read the the minute by minute update of the announcement of the Kindle DX. Bezos did have a copy of sheet music on the device. My wife has the Kindle and the print quality in daylight is excellent. The DX unlike Kindle 1 and 2 have built in support for pdf files. I'm going to guess they would need to have to update the software to make lead sheets easy to navigate.
