The only difference
Is power consumption. I turned in my FIOS bloodsuckers for W7MC which takes up way less power and I can change providers by swapping a cablecard. They of course can add their streaming stuff in there or partner w/ the likes of netflix, etc and get apps.
The cost should come way down--less than $50/box.
These boxes on Roku/ATV scale should be no more than 3-4 watts, and should be no more than $3-$4/month each. The killer is going to be what they charge for the master Tivo. If it's more than $20/month then it's a step backward.
If they hide them behind a TV, that means remote extender, I assume.
This will also mean the persons home needs to be wired for at least 100 and probably gig, and that means MoCA or ethernet.
Also sadly missing from and cableco DVR solution that I have had is media integration (roku/ATV) WITHIN the house. If that still isn't there or has some wonky MSFT interface, then just another mediocre step. If one of these bozos could actually get that right they could easily thwart Apple and Google, who are coming. Oh and Tivo in 5 years at their slothy development pace.
