As the preceding thread message indicates, I too relied quite heavily on your wisdom before pulling the trigger on the DR. Sorry to hear about your loss.
I was just holding the DR in my hand, and noticed that I sometimes held it in my left hand to read, along the bottom left hand corner. Sometimes, I'd lift it from that corner from my lap, and due to the weight of the thing, it seemed like I might be unnecessarily straining the bottom corner of the device (or its innards).
Any thoughts on whether the way you held your DR may be a cause of the malfunctioning/broken screen? Maybe it wasn't trauma but strain that has led to the screen issue?
