Long time lurker....I hope you won't mind me participating in this discussion.
I'm quite concerned about the aluminum body. Aluminum is a terrific thermal conductor and will match the temperature of its surroundings rather quickly. Yet, because of the mass of this block of aluminum, it will exhibit some thermal hysteresis. So, should you take the camera from an air conditioned hotel room outside to a warm humid atmosphere, it very well may become slippery and noticeably moist in the hand. I can imagine water condensing on the surface of the body. Moreover, in a cold environment, it might feel like holding an ice cube and you might even experience a frosty surface.
