I think the most significant benefit of the YARD stick is actually the combination with rfcat. Meaning - the ability to control a radio transceiver interactively using python without having to implement all of the rf chain.

I recommend watching Ossmann's presentation on rapid reverse engineering. I think his demonstration shows the benefits of this stick.
