When Jeff Bezos and company reported Amazon.com's earnings at the end of last quarter, they swore the Kindle was flying off the shelves. But I've never seen one in the wild. Or even heard of a sighting. Until today when I saw, thanks to Silicon Alley Insider, a photo of a girl reading a Kindle on the New York subway. Take that, Kindle-hater Steve Jobs. Have you ever seen anyone using a Newton on the subway?
