Back on September 9, 2009 - almost four years ago now - Apple introduced iTunes Extras, which allowed for the director's commentaries and other bonus features common on DVDs at the time, and now, BluRay. The original, OS X 10.4 Tiger-based Apple TV, was soon updated to support iTunes Extras, and it's musical cousin, iTunes LP. Then, on September 1, 2010, Apple announced an all-new, all-streaming, all iOS-based Apple TV 2. And iTunes Extras didn't survive the transition. Not only that, they didn't get added back with subsequent software updates, not even with the Apple TV 3 announced on March 7, 2012. As of today, iTunes Extras is still MIA. And it's super annoying.
