What this article does not say is the Vizio C-star has an HDMi input from your set top box so it can integrate your full cable TV line up with Google TV and the Play store. Thus with one interface you have your cable TV line up as well as hulu, Amazon Prime, Netflix etc without switching inputs. Basically its an Android 4.0 box that brings all this together.
Its pretty good and if I did not have a Silicondust Prime already set up on my home network I would get the Vizio unit. Its prett cool.
