Of the 8 reasons you listed why Al is allegedly superior, 7 are reasons that it's actually the lower-grade product and the 8th (drop resistance) is simply incorrect. To a first approximation, overall acceleration doesn't kill glass or batteries, it's the uneven application of force that kills them. I'd imagine that increasing the rigidity of the frame improves drop resistance a great deal.
