I agree for some folks it'll be better. Never said otherwise. I'm just, again, unconvinced it'll be the ultimate attractive feature. A well designed interface makes searching for videos easy enough, for example. Pulling up a TV schedule, seeing a program you like, highlighting it (with a wave of your hand) and pressing the 'record series' button is hardly a chore.
There are a bunch of things that are hardly a chore thats gone the way of the dodo.
I also don't see remote controls going away with the advent of XB1 because I don't think it'll offer the best interface for some uses. You can actually multitask better doing menial tasks with your fingers while thinking about something else too. As most folk think using their language internally, voice commands require you to think about what you are saying. If someone comes into the room and starts talking, I can answer a question while simultaneously pressing the TV's mute button. That's not a big argument against voice controls. Just another small thing that in my mind shows voice control isn't a huge deal. A marginal improvement for some, a big improvement for others, an irrelevant feature for others. I don't think it's going to be a potent USP or sound basis for the platform's business strategy. If PS4 offers many of the same features without voice commands, I don't think its perception will suffer much.
