I have dropped my iPad at least 100 times, maybe more. It's fallen off my bed at night countless times. I have a rug on top of a concrete floor in my living room and have knocked it off it's stand, had the stand fall on top of it. About the only thing I haven't done is thrown it like a frisbee.
I had this one time late at night when I was trying real hard to read something in the forum and I kept dozing. Dropped it 10 times (I counted) in a row.
This thing is better then a Timex. :)
I do have a silicone cover on it. That's all.
