This is almost a ridiculous question.
The D700 is a FAR superior model camera. Unless you wind up camera poor and not able to buy any lenses, you buy the D700 and never look back.
Not ridiculous at all when you factor in costs. And you have to assume costs are a factor otherwise the OP would just get a D3X instead of the D700.
A few things that make the D700 potentially less appealing will be that it will be replaced with a more advanced model later this year and costs WAY more than the D700. Also, I believe the auto bracketing on the D7000 is far superior, allowing for +/- two stops in auto bracketing and the D700 only allows for one, right? This would be a big deal for me since I take may pics for HDR. Have a feeling this will be "corrected" in the D700's replacement model.
Um, yeah, but the cost issue is about as obvious as it can be, thus making the point kinda like "well, durrr".
And very few people are going to wait (and likely spend more money) on the next model of camera for an additional stop in bracketing. (you shouldn't be using auto-bracketing in your HDRs, anyway)
So yeah... kinda a ridiculous question.
