I was reading up on DRM. There is concern by some that we creating a condition where the media products of our time may not be preserved for future generations, because of technological advancements and/or the loss of technology.
My chief concern with the new XBOX and PS4 is with cost. I don't believe the corporation spin on what will happen after the demise of the used game market.
As for ebooks, there is a difference. I can choose to be like my mother, and get the books downloaded, or I can choose be like me, where I buy the physical copy. Microsoft is not giving the consumer those options - there is one option - buy the digital product. Excuse me, buy the license to the game.
