Last year we were vacationing at the coast. The bedroom I was in had ceramic tile floors and one of those old-timey beds that was 3 ft or so high. I put my iPad on the night table and plugged it in. It was laying flat.
Sometime during the night my 3 year-old granddaughter came and got in bed with me. So of course she rolled off onto the floor. I think her arm caught my iPad because somehow it went down too. In fact the sound of the iPad hitting the floor was what woke me up.
She didn't even wake up (kids can sleep through anything even falling 3 ft onto stone) and my iPad ended up face down on the floor. Not a scratch, dent, scuff, nothing. Don't ask me how because I wouldn't have believed it. It must have landed just right.
Damage depends completely on the angle of impact. Some of us have been lucky, some haven't.
