I don't see this being a selling point, most people that would want those things only likley already own these things in other products. Only thing I can see is gamers that like these features, but how many of them wouldn't have gotten the xbox anyway? I don't see none gamers buying this for those features.
Then agian people bought PS3 because it was a cheap blue ray, so competativly if this was 500$ would someone buy this just for the none game features? --- currently playing Mass effect 3/Diablo 3 and soon to be path of exile.
