A basic rule of literacy is that ALL analogies break down when you try to extrapolate them too far. Market trends for coffee could never be used as an analogy for market trends for computers. First of all, there are infinitely more blends of coffee to choose from then there are OS's to choose from. And don't blame me for choosing a bad analogy, persia chose the analogy, I just tried to improve it. Despite your critism, I still think my analogy is better then persia's.
