I would not consider cracks "dents". I already mentioned the cheap 'ABS' plastic, they would crack (also it's not UV stable). You can look up PA6-GF30 (nylon, 30% glass fiber reinforced) tools and they survive ~2m (6 feet) drop tests. Laptops won't do that as their screens would crash. Here: a popular video[0] of some massive abuse of a multimeter.
Again, a good plastic with glass or carbon fiber reinforcement would have similar properties to al-mg body, yet feel cheap as most people consider all plastics quite the same. For example: polycarbonate, 30% carbon fiber would have tensile strength of 150MPa (which the same to cast aluminum)

- OJFord 5y agoNo, neither would I. I was agreeing with the commenter you replied to, that I'd expect a plastic laptop to crack, and a metal one to dent. If it has to be damaged, I'd prefer the dent. You said above that that was more to do with 'top finish' than 'material'; that's what I was responding to - how would you finish crackable plastic material to make it dent like aluminium/alloy instead.
