hedwards: Eh, it was more of a footnote that Apple ditched DRM when at some point after it had established itself as a monopoly, and before the DoJ was starting to nose around about why they were using their position to hurt the competition.
Actually in fairness to Apple, that's only mostly true. :) They had made moves to ditch DRM even before they grew to be the music giant they've become which took actually longer than people remember. People tend to remember the massacre the MP3 market became, but that process didn't really start until late 2005. Apple started going DRM-free officially in Jan 2007, mid-late massacre, but it took over 2 years from starting the process before they had all the publishers on board to go DRM-free when the dust had essentially settled. So going DRM-free wasn't actually some sudden reversal for them. They had already begun to establish dominance, but the roots of going DRM-free do predate the total capture of the MP3 market. Not that possible anti-trust investigations weren't something they were concerned over. ;)
Also remember it was the music industry like the game, book, and movie industries that wanted DRM. The irony is that Apple had to convince the music industry to let them drop DRM in the iTMS. Weird to think, but the music industry would've been quite happy for Apple to continue with its DRM. But then I've not seen reason to give much credit to the content providers for brains when faced with the dawn of digital distribution. :/ Apple could've even gone with simply a less restrictive DRM for its music. In some respects it was only because Apple was big in that space that they could make a DRM-free case to the music industry.
I would also like to note that the argument Apple used to promote DRM-free music to the publishers was that it would be in the end more profitable. Such arguments will be made for the other media as digital distribution of movies, books, and games become more prominent and eventually I see those arguments winning out.
So ... eh ... don't get me wrong, while I'm indeed a Mac guy, I'm far from comfortable with all of Apple's policies/actions. But given the end result of that particular era was a DRM-free music industry, I count it as an overall win for the consumer.
