I left my iPad on the floor next to the bed when my eyes got too tired to read. Unfortunately I then fell asleep on the edge of the mattress. Some time later I fell off the bed with a huge thud and woke up. It was as unusual sound, which came from my knee as it hit the unprotected iPad screen. In sleepy shock I got up to check the glass for damage, and to my amazement couldn't feel or see a single crack - except on my knee, which was now bleeding! I had fallen on the glass at the edge of the iPad, which saved the screen yet cut my skin quite badly. I must be lucky, because knees heal and don't need to be sent away to Apple for repair. Tests showed all buttons to be working on the iPad, the speakers are fine, volume control and everything else works like before. Further tests showed my knee to hurt when I walk. This anecdote was typed out on and sent from the iPad as part of a general test to make sure it works as well as it did yesterday. It's aimed partly in praise of the iPad's tough build, but also as a reminder to myself not to leave it on the fracking floor again at 3:00 AM.
