Well, my experience with Nikon cameras goes back to the first slr I ever owned, an N60, then an N80.
I got the D70s in 2005 and have been using that body nearly everyday. I put it through its tests.
But this isn't a nikon commercial, we're here to talk about the new Nikon D7000. This camera definitely feels like it is solidly built. You can tell by the natural heft, that this camera is pretty serious, not a toy like those plastic/composite bodied DSLRs.
I love the textured finished that helps you grip the body more firmly and securely. The view finder is VERY bright, clear and has nice magnification. The menus are easy to navigate if you have any experience with Nikon DSLRs or even some point and shoots. The button and controls layout is 100% Nikon. If you've used a Nikon before you already know where that button is.
I haven't used the U1 or U2 presets yet, that isn't really my style, so I can't comment on their usefulness.
The lever to activate Live View is pretty cleverly designed. Virtually no shutter noise even in regular shooting.
I also haven't gotten into shooting any video yet, just short clips, but even with that little use, it seems like it is well thought out. One thing I don't particularly like are the choices for af sensor array in af-s mode. You have the choice of the single center sensor or all of them. In af-c/a you have multiple options for greater flexibility.
My major pet-peeve is the little rubber flap (where your pinky finger will rest) keeps coming open when I am playing with my camera. This could just be from the way I hold it, but it seems like it should lock down more securely. I don't have much hands-on experience using the D7000, I only recently got and started using it. I have only gone on two out door hikes with it. So far -Great.
