Although I don't think it is OK to pirate anything, I have done it in the past (and very likely I'll end doing it again).
I certainly try to go for the freeware or pay for the software, but I find it hard with movies and music... I go to movies very often, but buying/renting is harder than just downloading. Same happens to music, sometimes it is easier to find the cd online, than getting it in a store (even online strores...)
I do think that piracy is some kind of theft, and therefore I'm trying hard to not do it. But sometimes I just can't...
