Whenever I see Gorilla glass strength demonstrated, it is always using impacts on the front of it. Not on the edges. This tablet looks like it landed on it's edge where the glass is weakest.
Also, Samsung advertises "Easy Grip" as a feature of the tablet. I'm hoping that is just something the Galaxy Tab IO Edition is missing, because it sounds like people that have that tablet have grip problems.
