I completely agree with Thom Hogan. I already had the D700 and knew that the D7K was not going to replace it, just back it up. In other words, I knew what camera to get or be the primary one.
I believe what Thom is saying is that if you do not know the answer to that question and then you should go for the less expensive alternative and grow into it, first, to put it politely. I think it is a “backhanded” slap type of comment that I would have never made.
