if DRM is a waste of time, then why are people still willing to use DRM devices?
I think that what is inevitable here is NOT the end of DRM, but the evolution of DRM into something that is so convenient and loose that most people will still use the devices. At which point, only the true-believers will avoid DRM.
This is common in technology evolution, as most people will put up with any injustice or bad design as long as they get some minimum of satisfaction.
