NOOK Simple Touch™ All-around Disappointment At first, I loved it. Conceptually, the Nook was just what I needed: lightweight, easy to read, uncomplicated. But it was a short-lived romance. Within weeks the screen became unresponsive or, even worse, would operate on its own, flitting between screens, jumping ahead or back without even a look from me much less a touch. I've been stuck on the same book for months--not because I'm a particularly slow reader but because the Nook won't close it or open anything else.
