I dropped my aluminum body Dell XPS 13 on a tile floor (it was in my messenger bag, but I don't think that helped much). It hit the rear corner and mushroomed the metal quite a bit, but nothing broke. I'm reasonably sure that if it was a plastic body it would have broke.

Most Thinkpads are not normal plastic. The W520 is carbon fiber and glass reinforced plastic over an alloy frame.
