I don't think you understand that the Xbox One is more than just a gaming console and that is part of the reason it will sell so well. There are people that couldn't care less about that and those are the people that will continue to game on their PC or buy a PS4. I don't want to put the money into a HTPC that I will hardly use and never game on. I want something that I can turn on, stream a movie or TV show from my computer over wifi or on Netflix/Hulu/Amazon instant video, play music or just hop into a game with friends and sit on my couch.
I still don't understand why is it so difficult for people to grasp the concept of wanting a piece of equipment to supplement your living room as a whole and not just another gaming system. Everyone's needs are different, that's why we have choices.
