Steve Jobs posted a letter to the community today talking about music and DRM. If it has not become obvious to you before, he painstakingly spells out the only reason why both Apple and Microsoft and a multitude of other companies have to wrap the media they sell in DRM.
You will garner from his letter that the sole reason DRM exist in the format it does today is to protect the multi-billion dollar movie and music industry. I understand the issues they are faced with and as a consumer I have voted with my wallet and only support indie artist. Steve Jobs
