The use of DRM in any form of media is short sighted. Limiting how a user can use what he buys is only going to frustrate legitimate buyers. Pirates will get their media anyways as people crack the DRM almost immediately. Suddenly piracy looks good to people who legitimately buy the media as the cracked versions of songs/movies/games don't have the limitations of the legitimate versions. I don't buy songs from any online service (ITunes or any of its competitors) because more of those services than I can remember have shut down their servers which stops all their music from working. When I buy something I want it to be mine, I don't want a license to listen to it as long as the distributor feels like keeping up its servers. Similarly I don't want to buy a video game only to have it install software on my machine that CANT BE REMOVED and also only be allowed to install it on my machine 3 times (this was the case with the game SPORE). The ways companies have tried to prevent piracy over the years have changed, but one thing that hasn't changed is it ALWAYS inconveniences the buyer, while it only inconveniences pirates for as long as it takes to crack the media.
