Since it would start saving us money pretty soon, there is another option.
Google TV is, obviously, a "bit" more expensive than boxeebox.
And neither of them does 100% of the "media center stuff" that would be ideal.
But in the same price range as Google TV, there is the option of these "roll your own media center" boxes.
I explored this idea a long time ago and I don't know why I abandoned it (maybe price, maybe forgetting to factor in the lack of cable box).
It's basically a half-size computer, with graphics and network optimized for video streaming, just as much (or as little) local storage as the google/boxee options, runs linux and/or windows (and can run boxee software for sure), can run a normal browser for Hulu/Netflix/what-have-you streaming without workarounds, has remote control all ready to go, and even a DVD (or Bluray?) drive for disc playback, etc etc.
I think this warrants further investigation, but it for sure involves more setup and involvement in maintenance than the other ones. And again, is probably about twice as expensive as the BoxeeBox itself.
Rambling on... this may not be the last entry on the subject....
