Is DRM Intrinsically Distasteful?

jelton writes: If digital media was available for sale at a reasonable price, but subject to a DRM scheme that allowed full legitimate usage (format shifting, time shifting, playback on different devices, etc.) and only blocked illicit usage (illegal copying), would you support the usage of such a DRM scheme if it meant a wealth of readily available compatible devices? In other words, if you object to DRM schemes, is your objection based on principled or practical concerns?
