I dropped my Vita over the weekend. Luckily, it landed on grass and was totally fine. These guys aren't dropping their Vita on grass. They're dropping it on a road. Over and over again. For science.
As part of their highly practical "drop test" series, Gizmo Slip let the Vita fall to the bitumen four times from a height of 1.2m to simulate the effects of the handheld, I don't know, falling out of your backpack or hands.
If you can get past the hypnotic slow-motion footage of the Vita bouncing, you'll see it's one tough little handheld.
