An experimental tour-de-force: Entanglement between glass bead and light

I've read a few articles by Chris Lee, and I normally like them quite a bit. However, IMO there's something missing from this one, like how does this experiment push the frontier of quantum entanglement research? Is this the most complex entangled state ever created in a lab, or something like that?

this could be used to build an exceptionaly high tech abacus
