I agree 100%, this is a digital N80. The only differences that I'm aware of right now are a slightly larger body, slightly faster flash sync. And of course all the digital stuff. I'm not sure why Nikon would call this model D100, maybe for marketing purposes, they don't want potential buyers who own F100 to think that they are stepping down in terms of features (Even though they are).
All in all though this looks like a nice digicam, if I had an extra couple of grand I just might get one.
