Some product manufacturers do things like list specifications or show you pretty ladies to get a piece of your mind. Others use a product as a hammer to prove its durability. MobileDemand did just that, using its xTablet PC to hammer a dozen nails into a board complete with an accelerometer to show how much impact the Tablet PC was taking “without a glitch.” If this doesn’t prove you can use the xTablet PC to build a bench, we don’t know what will. Video after the break, of course.
