I do not know how the survey was conducted, but I doubt it was truely random. If they went one type of store, or surveyed online that is not random at all. As you probably know a random sample must have equal oppurtunity for every ps3 owner to be asked this question. The survey does not come close to giving every person equal oppurtunity.
That is why some people are not taking the survey to seriously.
