Your premise is skewed, Cspace is not a 'software download. It's the apples and oranges thing again. In my world proposals created for packaging machinery come with escalating costs for cancellation of a purchase order. What is the difference between a 10% cancellation charge and a 75% cancellation charge? The percentage of completeness of course. Our customers generally accept our terms without argument, so they also agree that an increased amount of completeness is of greater value. You're simply not in the real world, is Cspace like a software download, or a million dollar packaging line? Any engineered or manufactured goods at 99% complete are obviously more valuable than at some lesser degree of completeness.
