>There are many benefits the D700 has over the D7000, like a much larger view finder, I provisionally disagree with "much larger" - I handled the D7000 about 10 days ago - and expect to test drive it tomorrow. Comparing D300s and D3s (I use both side by side) the D3 series have significantly more minus viewfinder magnification than the D300 series, reducing the apparent size difference to about 12.5%. The D300 series have viewfinders about a stop brighter than the D3 series. Minor differences are the viewfinder on the D3 series does not show brighter screen brightness or reduced depth of field than about f2.5 - slightly better than the f2.8 with the D300 series. Overall I prefer the D300 viewfinder. The D7000 seems to have the same viewfinder as the D300 series. The extra resolution (when needed) of the D7000, 100 base ISO, twin card slots and video are some factors to consider.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
