You can't have a shelf full of Kindles

I recently heard that fiction is the most popular category of books downloaded for Amazon's Kindle, and within that, romance novels are the most popular genre. As a friend wisely pointed out, this is probably so people can read romance novels in public without being embarassed by the cheesy covers. The flip side of that is discussed in this NY Times article. My feelings about the Kindle are mostly neutral, but of all of the anti-Kindle articles I've read, this is the one that speaks to me the most.
