I see both points to this.
I have many times tried a demo of something and decided I liked it enough, and felt it was worth the price they were asking, I made the purchase.
On the other hand, Ive tried things I felt simplt were not as advertised or not worth the asking price.
But I think there is a difference. in this case its a "potential" customer.
But I would also agree with madtownidiot to a certain extent.
Meaning, in our cases, we tried said software and were potential customers at that point, who then turned to a paying customer.
Sadly, most Pirates do not have that mindset. They never were, or ever will be a "potential" customer, at any point.
They are just after whatever they can get at no cost to themselves.
So in a sense, for some of them, there was nothing lost as they would never have considered the purchase in the 1st place.
Still, this doesnt account for all that pirate software. Some would potentally buy the product.
But once they have a "free" copy thats working 1/2 decent, , why spend the cash?
In this case, it is indeed a lost sale.
