"how many 'normal' people do you know have SDHCs, compared to people who have miniSDs?" I think that many people have different kinds of memory for their cameras, and they go buy the kind required by the camera. I don't think that the kind of people who buy x kind of memory splits among "normal" and "abnormal" people. I don't think that sdhc memory is harder to use than other kinds of memory in any way, as your statement implies.
