David Berlind has a 3 minute whiteboard presentation on CRAP (content restiction, annulment, and protection), the new term for DRM. His advice: don't buy anything with CRAP in it.
I like these little whiteboard presentations. They're a lot like screencasts, short, simple to make, and easy to watch.
As long as we're on the subject of CRAP, check out the analyses of iTunes U, Apples attempt to corral universities into the iTunes/iPod silo, by Jon Udell and Gardner Campbell. Jon got a load of crap (note the small case) from Mac zealots for daring to criticize Apple.
