I don't do any in-camera processing so I can't comment on that, but I also love that digital provides essentially instant images. And I am extremely happy that I've spent the money to upgrade to the D7000. I see the AF fine tune as a real bonus: my 16-85 VR didn't seem quite up to par until I dialled in a little negative tuning, now it is superb.
By "old AF Nikkor" do you mean your 50mm f/1.8? I have one of those, but I have to admit I don't think I've mounted it yet on the D7000. Maybe I should try it.
