I am not surprised about Tony Northrup's examples and conclusion. We have both a Canon and Nikon system, and noticed already several years ago that there is always a difference of 1/3 (or more) of a stop in the results of our Canon and Nikon digital cameras, using the same settings. Since Canon installed "Auto-ISO", I used that and stopped thinking about ISO when I shoot digital, I only think in the categories of less or more noise.
I think ISO (if correctly implemented) made some sense in those days back when a lot of experienced photographers went digital, because it helped them to get a certain feeling for the digital work-flow. But that's over now, Tony N. is definitely right.
