Cost reduction will come from three factors (in increasing order of significance): Improvement in yield Economies of scale New, less expensive, manufacturing processes Canon has been hammering away on #3 and their success has helped achieve #2. Everyone else is lagging behind for now. Just wait until others begin to catch up. We ain't seen nuthin' yet. -- Mark Roberts Photography and writing www.robertstech.com
