Went to bed reading. I put it on the other side of my bed, safe from me i thought. In the morning I woke up, rolled over and felt something under my head. Under my groggy half asleep state I heard a tiny crack. I bolted up like the time I felt an earthquake hit. No please no. Slide the switch. Arrghh. Lines everywhere. Even worse, my incriminating custom screen saver is stuck right there and not going away. Busted!
Lesson: despite what the commercial tells you, your kindle is very breakable. Treat it like the delicate egg it is.
