Yes, it has a metal body. And that's why it has the worst GSM reception of all phones (well, maybe iPhone is worse, I don't know). Because of that d*** metal body it does not only feel dead cold in your hands, but is also pretty much useless as a phone (just touch it to watch the bars go down until you lose the carrier network). Oh, and it is quite heavy, too.
The hw keyboard isn't on par with the N900 either.

Simply forget about the N950. Nokia cancelled the device for a reason.
It's a nice developer device if you don't have to rely on it as a phone, though.
