About the metal casing, three naive questions here: - Does it allow thinner casing than, say, polycarbonate (or whatever was the synthetic material used on the N9, and maybe the Lauta if I remember the pictures correctly), and therefore smaller overall size? The reason I'm asking how it compares to the N9 material is I remember it looked great and felt even better in the hands, it also aged relatively well in terms of signs of wear.
