We have a bunch of Surface Laptops and Surface Books (looove the books) where I work (auto parts factory) that have survived better than they have any right to. I dunno wtf the previous IT was thinking getting them. They have 8 million magnets and are constantly covered in weld dust. But they keep right on working... shorting out power bricks and docks as they go though. In the process of retiring all of them but I have already cleaned up and let several people take their units home as they still get 5-10 hours of battery out of them and have no other issues. It is kind of wild how durable they have been.
