We've never questioned the rigidity of Panasonic's Toughbook line -- after all, we've been shown just how rugged these things are time and time again -- but a new video from the company is just too clever to pass over. Sure, it hardly makes any clearer what's already clear, but just in case you were still having doubts, Panny's Toughbook line is mighty tough. As in, tough enough to survive being towed behind a snowmobile in bitterly cold conditions. Unfortunately, the company only shows the screen lighting up after the ride's done, so there's still the possibility that the keyboard is totally shot -- but hey, props for being alive at all, right? Have a look yourself in the video above.
