I think the difference is that 95% of Paint Shop Pro users bought it and that 95% of Photoshop users have a pirated version. Photoshop is 695,00$ in Canada and PaintShop Pro v8 is only 149,00$. Sorry but I can't afford a sofware of that price if I can have one for 1/4 the price. It is the same thing with 3D modeling software. I don't have the money to buy 3D Studio Max or Lightwave, so I'm working with Wings 3D and the Carrara Studio 1,1 (free with a magazine). And with practice, you can do what you want with Paint Shop Pro. That's my 2 cents (in Canadian money).
