Yes, I think we would agree that the higher the technology, the greater the information/experience/effort required to make the best choice.
That is why there are consultants, yes? A CompuSave salesperson does not a competent consultant make.
My point is that in the mass market most folks lack information/experience/effort to make the best value choice for their uses. Ergo MS has a larger market share than otherwise.
You, of course, politely disagree.
