Thanks for that post Ray, I went in a similar direction a couple of weeks ago and havent looked back.
My best friend bought an 800 and it was tempting to keep up with the Joneses' (as they say where I come from) Common sense prevailed, I dont print much and have no interest in video at all.
So a new lens for the 700 became my mission but I already have the 70-200 2.8 so where could I go? After a friendly discussion with her indoors, (which would have been ignored if neccasary) plus a little help from my flexible friend I bought the 24-70 2.8 the one which I had been dreaming about for some time. Result - very happy. I love this addition, cant take it off the camera. For my modest needs the D700 and those two lenses are all I need. Well until the "next time" shall we say.
