I recently bought a D7000 as well. One thing I really like is how sturdy it is, with none of the plastic feel of my previous camera, a D80. At a family reunion last weekend, I wasn't too worried about letting the little children (three years old or so) take pictures of each other. I just wasn't worried about the 1 1/2 foot drop. I also like that I feel like I can just throw in in a bag without babying it too much. In that vein, I use two lenses, a 35mm and 85mm prime 95% of the time which are both very solid metal lenses. I wouldn't do that with the 55-200mm.
