That's a great list and a very useful post. Personally, I would be more inclined to buy the D70, if only because of the 1/500th sec flash sync. For shooting sports and outdoor portraits, that's an incredible feature to have.
I also believe that the newer sensor in the D70 has to better than the sensor in the D100. I don't have any evidence to base this on. But it makes sense. Of course, you mention the D100 processing in your post and that's an important consideration. Even if the D70 sensor is the best ever, if the processing doesn't deliver the results you need, it's no good.
There was one point in your post which I didn't understand:
"D100 captures True colour rather than memory colour therefore the D100 colours are less saturated"
Can you explain this to me?
Thanks for the great post, and thanks in advance for answering my question about True Color vs. Memory Color.
