Not a surprise, but still nice to see the trend continuing.

My preferences are simple: I like to read fiction on my Kindle, and I like to read nonfiction on paper. I like to sink into my fiction (which the Kindle seems to make easier than paper) and I like to read my nonfiction with a pen. If they could develop a quality, reliable stylus-based input for the Kindle (which they won't, because I don't think many people want it), I'd be happy to eliminate most paper books from my library.
