Well it's obviously a move in the right direction, though how much difference it will make is yet to be seen.

Way I see, people who care about DRM aren't using iTunes and wont until they make all of their music DRM-free (and maybe not even then). People who are using iTunes probably aren't bothered, unless they've directly ran up against it when copying music. So I'm not sure how people are celebrating because they're directly effected.

But regardless, information should be as free as possible, so yes, a good move.
