DRM should be used very sparingly, if at all, because it often acts as an incentive to pirates so they can avoid jumping through hoops just to play their games. Spore on the PC is perfect evidence of this. Having famously limiting DRM, it became the most pirated game of all time (http://torrentfreak.com/spore-most-pirated-game-ever-thanks-to-drm-080913/). That seems to me to be working against both people's enjoyment of the content they buy and against the goals of preventing piracy. It is also noteworthy that Apple iTunes is converting to an almost entirely DRM free system (http://www.apple.com/pr/library/2009/01/06itunes.html), and already have to some extent with no trouble (http://www.apple.com/pr/library/2007/04/02itunes.html). Sales have not plummeted, and people continue to buy music legitimately with the same zeal as before. Thank you.
