“There’s no good answer to designing a “good DRM.” Or rather, no DRM is good DRM. iTunes is instructive again in this regard: Apple sold a billion tracks in three years in spite of its DRM, not because of it. No Apple customer bought an iTune because of the DRM. What’s more, every track in the iTunes music store can be downloaded for free from P2P networks. Apple proves that you can sell music without DRM all day long — all adding DRM to Apple’s music does is give Apple the ability to abuse its customers and its partners from the labels.” – InformationWeek
