I have until October 2007 to return the 717 with a failed sensor, and Sony will repair it free. 717 sensors around the world have been dropping like flies. Mine continues to thrive, and it was one of the first sold. Yesterday, in desperation, having been told it was humidity that made the sensor fail, I turned the shower on full blast, closed the bathroom door, and left the 717 in there for a couple of hours. No luck. It's still going strong. I really love this camera.
