I agree, Team Speed.
Personally, for the type of photography I do, dynamic range doesn't matter much to me at all. Very seldom am I trying to create images that include very light areas as well as very dark areas - in most cases, I prefer to capture scenes in which almost everything in the frame is right around the mid-tone, without a lot of range from bright to dark.
In other words, I usually am trying to make images in which the histogram would represent a perfect bell curve, with no part of that curve extending to the left edge of the histogram, nor with any part of that curve extending to the right edge of the histogram.
However, getting images that have perfectly resolved fine detail with no grain at all, and very smooth blurred out backgrounds and/or foregrounds with no grain at all - now that is of extreme importance to me!
I think that maybe on some kind of scientific, technical level, ISO and DR may be inter-related. But as far as the actual aesthetic qualities that I enjoy when viewing a photo, they are completely different, unrelated qualities.
"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "peace of mind", NOT "piece of mind".
