article from the Register. Apparently, the author of that article "has a beautifully concise explanation of why DRM would fail in a free market: it costs more, but delivers less."
I'm not ready to jump on the DRM is evil bandwagon quite yet, but I think it has been used so heavy-handedly, and so intrusively, and even so deceptively (such as for content people think is theirs, but turns out to be non-permanent) that it's a real problem. It's holding back a lot of revenue streams for content providers as well as technological advancement of digital content in all forms. Including mobile technology, of course.
I'd be happy to launch my own full-scale rant about DRM, but apparently that article has plenty.
