Chris Pirillo relates the difficulties that his wife had with various music devices (the iPod shuffle being one of them) - all because of DRM. The story is worth reading in its entirety, but here's the kicker for the management types who think DRM is "protecting" them:

The story ends up with me listening to my Shuffle of music and happily copying all that needed to be copied. I will have to catch up on the latest podcasts and audiobooks from my computer at home until I figure out the problem. I will confess for a split second thinking. "Dang, if I still had a CD player I could have burned the audiobook to a disc and listened to it that way." OMG how awful was that? I have three of the latest devices and I'm thinking of burning a CD. Now think about my poor Mom, how would she deal with all this tech drama. I'll tell you how, she wouldn't "fool around with it" until it was one button sync and play, a better alternative than whatever she uses now for music and more reliable with more features. If you find that device and the software that runs it please forward me the info. I need it. What devices do you use and how easy are they to work with?

Shorter: "Most people won't buy it at all". All that protection you get from DRM? Yeah - it's protecting you from revenues.
