Gorilla Glass is one of those rare product features that is so much better than the alternatives it's like magic. It's not strictly indestructible if you drop it, but you can just chuck it in a bag with your keys and not worry about it. Unlike polycarbonate.

Plastic-bodied laptops flex a bit more than metal ones. If you've got a large one and you regularly pick it up from one side the flexing can gradually crack the PCB. I agree that aluminium scratches up rather badly.

(Handily the Dow Corning website will list products using it, so you can avoid worrying about whether the vendor is using an imitation toughened glass)
