I have a K1, and a K2 Kindle, and played all sorts of games with book lights trying to figure out how to read books on my Kindle in low lighting.  One of the hidden warts of the Kindle, is that while it's performance in bright sunlight is superb (actually, the brighter the light outdoors, the better the performance) - It's performance with a direct book light is horrible.  You end up always having to try and read around the glare of the book light.  Enter the Kindle App for the iPhone.  I've read about a twenty books on that application.  Devour Science Fiction - nobody I know has been more eagerly anticipating the iPad for book reading.<p>For Outdoors, Bright Lights, Beaches, Camping, Burning Man (really!) - Nothing beats the Kindle for reading books.  But, in dark offices, in bed at night, on the subway - Apple wins the day.
