I went from a D200 to a D7000 and am very much enjoying the clean higher iso capabilities I now have. I took some old SD cards and created/saved custom settings for portrait, landscape, travel, sports, movie and point/shoot. I can quickly load these into U1 or U2 to give me quick baselines for different shooting solutions. I used 16mb SD cards from an old Palm Pilot for this. Each card is clearly labeled. I am using an eyefi card in slot 2 where I save basic jpg files. Card 1 is raw images.
I was looking for the D300s or its replacement, but the D7000 was too good to pass up.
