Sony's touch screen makes the display (which is the most important feature in a reader) inferior to Kindle's. Also it's expensive compared to Kindle.

Well, Kindle is $259 and Sony is $273 at Amazon.com, so the price difference is negligible. Don't know about the screen quality, though. Real side-by-side comparisons would be interesting; assuming that Kindle is better, how much better it is?
