Apples track history of listening on the iPhone is, for lack of a better phrase, piss poor and even if they do listen, it takes years to "make it through the machine". I'm still anxiously awaiting a lock screen which allows you to see information, upcoming appointments, number of emails and whatever information third party apps want to disclose via some method of configuration.

I'm not holding my breath.

I also fail to see the x-serve analogy.
