I think no DRM is impossible. And as ysss pointed out the moment you add any restriction it counts as DRM. Even requiring a user to enter a code is DRM.

Just like there can't be a society this size with no copyright or patent laws. When societies were small if people screwed over each other. You knew. Now people can screw over each other easily, and in some places where the concept of the individual is extremely promoted then it's a "me, me, me, I don't give a **** about what happens to you".

The point is to pick a DRM system that doesn't **** off the user. And in Nokia's case, if they want to keep the community (unlikely with the way they've been acting) they had better choose a good balance between the two. Not, "you can choose a DRM system with restrictions, or a non-DRM system with no restrictions". If I want that setup I might as well go to Android or even the iPhone if I'm going be fighting the system (OS) constantly.

And I love xkcd comics.
