ps The extra buttons on the D7000 are also really handy. I don't find myself diving into menus while shooting, which I was constantly doing with the d5100.
I have set up my custom shooting mode for my shooting style. If my kids borrow my camera for a few minutes, when I get it back all I have to do is switch to my custom shooting mode and I'm ready to shoot again. This feature alone is worth a lot to me.
