At this point, I think that DRM is driving people in one of two directions. They either refuse to use the product, as a matter of principle or because they have been bitten by overly restrictive DRM; or they bypass the DRM altogether, either for reasons that should be legal (the ability to use a product they purchased how they wish) or for reasons that shouldn't be legal (the piracy angle).

But I think that's a product of poorly implemented DRM. A lot of people buy and sell books on the used market, or they donate books to libraries and charities for fund raising; or they lend books to friends, textbooks for studying or novels for discussing. I believe that part of the reason for this is because noone knows how to handle these usage scenarios in a medium where copying data is easier than moving data from place to place, yet there is also an undeniable desire from at least some publishers and authors to move to a one-book, one-reader model (that is especially true for textbook publishing).

Over all, I think that DRM is a good idea in the sense that locked doors are a good idea. They allow people to trust each other because there is a token barrier. Yet I don't think that the current models for DRM are a good idea because there are too many restrictions and there are too many pitfalls. Current DRM models are more about distrust than establishing mutually agreeable boundaries.
