As many positive things as I have heard about it I have one question: will we ever actually see this as an actual product? I feel like I hear about so many cool things which never come to fruition and I have a nagging feeling that this might be one of them. Why? Because, as I've read, the companies would need data centers to manage all of these connections. What interest do these companies have to risk all of this money (a recurring cost, might I add) when people probably wouldnt spend more for it? I dont profess to know, so can someone who has actual information enlighten me?
