go read this. It's Cory Doctorow talking about why DRM is bad. I agree fully with every point he makes (except the last one wherein he posits that M$ should put out a good product -- I figure, why break their track record of producing crap?).
Perhaps someone else linked to it elsewhere, I can't recall seeing such, though. I just saw the link on Lessig's blog.
And, incase you're afraid of techiestuff, this article is very approchable. It doesn't rely on any prior techie knowledge.
