Hi Rafe, hope you don't mind me pointing out a small error in your otherwise thorough [pt1] review.

The material which surrounds the glass display is in fact metal, not plastic. This metal bezel is then joined to a metal plate which the glass is bonded to. The glass and the metal in this area are the main contributors to the weight increase, in addition to the metal sliding mechanism (N85 slide mechanism is also metal)
