The engine out will likely cause some swirl at NASA, the Air Force, etc. It will be interesting what the turn around time is on the Root Cause and Correction Action analysis for the engine going out. At first glance it isn't a systematic problem, the other 9 Merlin Engines worked fine.
SpaceX keeps doing a better job each launch of sharing their launches. I have heard from a reliable source that the cameras are going to be HD a few launches down the road (when they move from Falcon 9 v1 to v1.1).
The video of stage separation, Dragon (payload) separation, and panel deployment are all awesome things to see live because they represent important visual milestones for the mission. In my perfect world, all missions would have cameras at various stages in order to visually record how events occurred.
