Also interesting is the reasoning behind capturing parts of the rocket (and it is only parts) in midair. ULA say this is because the expensive bits are small, and essentially imply that they can get most of the 'wins' with not much effort when compared to SpaceX's "land it on a boat" approach. This may well be true but it seems SpaceX's approach is thinking in wider terms of the re-usability required for frequent space flight, rather than cheap space flight.

I have a keen interest in space flight and SpaceX in particular, so take my opinion with a pinch of salt, but this article reads to me like SpaceX are well over a decade ahead of the ULA, much more forward thinking, and overall the more exciting player in the commercial space-race.
