Since one of my primary uses is aerial photography, where pixels and resolution count heavily, I have since transitioned to a pair of D800s. But I still remember the shock I felt when I moved from the D200 to the D700. After viewing results of my first test shots, all I could say was WOW! There are still times I kind of wish I had kept a D700 and MB-D10 battery pack for sports, but I did what I did.
You are embarked on a wonderful journey as you employ your D700 in one situation after another. The camera is solid -- except for questions about the hot shoe -- and will absolutely amaze you for a long time. Concerning the hot shoe, I urge all D700 owners to get a flash bracket to take the strain off of the shoe and to move the flash off the lens axis for better lighting.
Enjoy your D700! And by a few months -- welcome to Nikonians!
I feel the D700 is to FX what the D300 was to DX - an excellent combination of features, IQ, handling, robustness, and price. Once you get to know the D700 and its ease of use and great handling, it will feel like an extension of your body.
If your shooting style is such, you may want to try the grip with the EN-EL4a battery...lots of fun shooting at 8fps! Not just for action shots, but also handy for hand-held HDR shots.
I can add my support to that, the D700 is still a great camera that does most things very well indeed. Now looking a bit short in the pixels department but then I look at the images and think, "What more do you want"
