I purchased these products IClone, Character Creator & 3DExchange, so I have no concern for a freemium type model, nor do I think this would kill all sales. If I can buy something in 3 minutes or create it in 3 hours, I will take the 3 minutes for $10 or whatever any day. Someone else with more time on their hands than money might create their own items, but these same people are probably not big spenders on content (students for example).
I was turned off by DAZ's model of giving you the car but the gas is $200 per gallon if you want to drive it, or even just sit in it. So much, I never even installed their product and chose IClone.
