bumpkin, I think you are right. But I also think that (to a fair extent) it currently tends to be older people that are more reluctant to change. But I'm not saying that it is specifically due to age, rather younger bods have been brought up in a much more dynamic world and are much more used to change (and I expect them to carry that "comfort with change" through to their latter lives).
In my case I've worked in IT for nearly 45 years and so am probably more used to change than many (of my age). Even so, I find assimilation of change more and more of a chore (partly because of lack of time).
