Steve,
I have two different versions of the Kindle--the first and second versions, thinking about buying the Kindle DX. The Kindle II is frankly awesome--I have more than fifty books on it, to include a whole bunch of out of copywrite sci-Fi H.Beam Piper's collected works are available for free, as are EE Smith. (I cut my teeth on these books). Still among my most appreciated fiction. The Kindle I had some ergonomic problems that have been fixed on the Kindle II. Only problem is very poor image resolution, and no color. But on the Plus side no screen glare, and easy extremly easy on the eyes. I read the Wall Street Journal on Kindle I and Kindle II and they are extremely easy to absorb at Breakfast.
Hope this helps.
Kevin
