The title sucks, but the article itself was balanced and informative.
It is interesting that Amazon's big push to get new e-books has apparently largely resulted in many more non-fiction titles than before. Most are not in principle exclusive to the Kindle, but I wonder how many other e-book sellers will pick them up.
Since Amazon does not have exclusive rights, it is possible that they are responsible for more fiction e-books being available these days too. This might be the case if there has been a surge in new titles over the last 6 months or so, in anticipation of the Kindle. I don't know if there has been a recent up-tick in new releases or not.
