There is considerable space between the belief that IBIS is useless and the conviction that it could be a huge win, and I suspect quite a few of us are somewhere in the middle...I have IS lenses and I use and value them. So for, me IBIS might be nice, but it would be something short of a huge win.
Unfortunately, it is a sign of the times we live in and the nature of internet boards that many people would rather argue than discuss a topic.
I do appreciate those who took the time to provide respectful answers to my question. I hoped that by asking for input, I would get some different perspectives that would allow me and others to make an informed decision about the value of IBIS or more accurately, about the advantages of waiting until Canon implements the feature.
We all have to make our own decisions. Mine is that it is not such a useful feature to me to compel me to wait for it's implementation before purchasing an R camera.
