Secretive X-37B spacecraft back on ground after 7 months

I wonder if there's anything other than politics (the X-37 being an abandoned NASA project) stopping NASA from calling up Boeing and putting in an order for half a dozen of these to replace the shuttle fleet.
I have to admit, though, it's smaller than I thought it was when I wrote my original comment. I had this confused with another one of NASA's experimental spaceplanes.
It might make a good substitute for the ISS for housing small automated science modules. (ISS may be deorbited in 2015, or maybe 2020 or maybe…)
I suspect its actual use will most definitely NOT be the militarization of space. The weapons platform will be deorbited from the transport vehicle before commencing lethal operations.
I don't think it would make sense to use it to replace the launching payloads and humans role of the shuttle. Since the X-37 needs a DeltaIV to launch it. Easier to just put the payload or a CEV on an expendable launch vehicle (Delta IV, Falcon 9, etc).
On the other hand it seems purpose-built for a science experiment platform, and possibly for robotic repair. NASA would do well to buy some for its science directorate. NOAA would also benefit from the chance to test their sensors on-orbit before integrating their big, expensive, weather satellites.
