Both very valid and good points. Being in charge of, and being able to modify, your MD is essentially what i was referring to in my last paragraph. And if you are a VDR user then I can see why loosing that would be a big hit.
How do you deal with watching liveTV using a media player? Does the TV signal, whether it's satellite, freeview, cable, whatever, still go to the core?
Also do you lose the onscreen orbiter? If yes, while not a showstopper, I would say it's a disadvantage, it's great being able to do anything from anywhere.
