I must admit that I pirated one game, and I loved it to death. I wish I'd paid for it. Plus I was too afraid the company would find out I stole it if I used the online content, so I didn't quite get the full experience. When I get some money I will probably buy it.
As for music, most of my library is pirated. But most of it was my sister, who owned the computer before me, and a good chunk of what I downloaded I probably wouldn't buy if I went to the store and listened to it first.
As for overpriced things, well, I'd have to say pirating them is fair. I would never have saved up enough money to buy Flash, which is like $400 even with the discount I could get. Plus I'm really quite good at it and plan to give to the flash community. I even bought a book on how to program on it from Adobe.
Pirating in general is not nearly as bad as stealing physical objects imo. Plus, it's a lot easier to get caught.
On the other hand, I plan on being a programmer, and I wouldn't want anyone to pirate one of my products, but whatever, it's inevitable.
