We're insulting it because the XBO's cable box replacement..whatever is going to be much more expensive than, y'know, regular TV, Annd if you already have a TV subscription, well, fuck you, you're paying for this shit too. Nobody would be angry about the live TV feature if it didn't cost us money, or at least a lot fewer of us would be.
Also, one thing I notice nobody has addressed about this: What if you have multiple TVs in your house that you.. well, watch TV on? Are you going to need a separate XBO for every television in your house if you intend to watch TV?
