Roger,
I hear what you are saying. In my time here, I have heard so many put downs to the ZS---one day, well after that big lightbulb went off over my head, it became abundantly clear to me that many of those put downs were coming from mouths that did not understand it at all. I'm so grateful that I did not listen to them. That's all I want the OP to realize. And he should realize as well, there's plenty of other awesome photographers who have been successful without using it, as I'm sure you are well aware.
Chuck
