I think the example of Windows XP is a special case, as every computer has to have an operating system. So if you can't cadge a friend's install disc, you do have to buy one for yourself. That's not the case with a program like Poser, where someone might accept a copy from a friend for free, but wouldn't bother buying it otherwise. As for REAL piracy, take a wander round downtown Bucharest sometime. In many countries people are driven to piracy because they simply can't afford the prices that are charged by big western software companies.
