One of Ming's comments bothers me: "The D600 is full frame for the masses; if you’re not a pro but you’re itching for an upgrade from your D700 or D7000, this is probably what you’ve been waiting for."

In your opinion, is he referring to build quality, image quality or both?

I know some Pros that are considering the D600 as well, so I'm not sure what criteria he uses to define 'Pro'.
