Most people say that you shouldn't sweat the small stuff, but Apple takes pride in finding a relatively small annoyance and finding a way to ease it. The newest issue the company wants to take on is that small annoyance where you're not too sure if you should call or text a friend.
The trouble that we foresee with Apple's patent on this is that it isn't automated enough. This is a kind of system that would work a lot better with either the social network of Facebook around it, or the automation of Google Now. Apple's vision seems to rely too much on users to put in all of the information of where they are and when and what to do. There is some automation, for example if you're at a concert, the system will figure that out based on your GPS, clock, and microphone data. But, we're pretty sure this system would be better to be based on GPS and public events calendars or even your personal calendar, rather than having to tap your device's microphone.
