There are some very interesting point in all this. I think it's right what poeple have said about average users wanting the latest and greatest even when they don't need it.
DVDs are interesting. Do people pirate new films because they are new, or because they are expensive?
I know there is little point in pirating a DVD you can buy for £7 in Fopp, but that might have something to do with it not boing brand new. Even though there is a good chance it is a much better film than some of the big new releases.
I know that when i was at Uni i used to download ripped films, not because i wanted them, but because i could. I don't think i ever watched them. They were rubish quality, Divx 3.11 was new at that point
