One of the strengths of Nikon is compatibility. I have a FE and F3 film cameras with 28mm, 50mm, 135mm and 200mm and a 600mm Cat lens. When I finally replace the old steam driven bodies I'm probably going to get a D80. I think I'm right in saying that the screen of the D60 is only for functions and settings and not a form of viewfinder, which I've now got used to with my Lumix "Bridge" camera.
I will be choosing, probably, the D80 because of this screen, but any of the Nikons will do as I can still use all my old lenses. I'm led to believe that using these old lenses will actually give a "step up" of 1.5. In other words, the 50 will become a 75, the 135 a 270, the 200 a 300 and the 600 a 900mm.
The only other thing that's come to my attention is that too many people fixate on the number of MPs. I can't remember which model it was now, but only a couple of years ago the main Nikon used for all types of sports photography only had 6MPs and yet was used by most pro-sports snappers.
