CF reinforced fiber is not cheap plastic by any margin. I've owned alu-slab macbooks (personal) and company-owned thinkpads for a long time. If you bump the macbook, you get a permanent ding. Nothing happens on the fiber for comparable force (unless you literally crack it). If you flex the notebook, the alu can be permanently deformed. The "cheapo plastic" will easily take a ton of torsional deformation without complaining. It's a very functional chassis in my eyes. And I love the boring look honestly. I'm kind of disappointed that recent models switched to a more grey-bluish look.
