Pretty awesome video, but it looks like they cheated a little bit by weighing the back of the device, so that it would land on its back rather than screen. An iPad 2 weighs 1.33 lbs, and has ~0.5 sq. ft of surface area when flat, which according to this NASA applet [1] means its terminal velocity is 12.2 mph (17.8 ft/sec). A drop at 12 miles per hour onto its back is probably not enough to destroy the iPad whether or not there is a case on it.
