The D700 was the body for which I had been looking for about 8-9 years. My first DSLR was a new D100 back in 2001, and even through around a half dozen other Nikon DX bodies, including pro and prosumer, I always missed something. I was always looking for a digital F100. (Sold the F100, kept the F5--go figure.) I finally got it. I really "think in 35mm/FX". (Some people can "think in B/W". I've tried, but I'm not there yet.) The D700 "fit" me so much, that I bought a second body--the first time I EVER did that! Sometimes something just feels like "it was made for you". That's the way the D700 is for me. It's an intangible.
I drive rental cars several times a month. A couple of months ago, I got in a rental that had "that feel"--like it was "just made for me". The next time I look for a car, I'll probably look closely at that brand and model. Sometimes manufacturers get it right. Nikon nailed it with the D700. That's why I really don't care about its successor. I expect to keep the D700 twins and have shutters replaced when needed. They're that good--for me and my needs. Your mileage may vary.
