Well I think you have to think for yourself here. DRM is phased out because custoners do not like the incompatibility problems it serves. So why it stayed in Vista is questionable.
When a mother for instance tries to copy CD from a TV on a computer, because she does not want peanut butter in the VCR, she is rewarded by modern industry with an incompatibilty problem, called DRM, and she tries all this in vain or has to go into lenghts, and even then it cannot be done legit. That is why these solutions are good for industry, not good for consumers (users).
