I think the grip feels 'thick' as well, it's odd to start with, but you get used to it fast, and all the other ergonomic features of the camera and menus were such a relief to me that it's easy to forgive the fact that it was made for people with big hands!
Have you taken a CF card with you and taken some shots?
My dealer thrust one into my hands last October and said 'take it away for the afternoon' . . . I was lost (and so was my Nikon gear).
