Can Siri carry on a 'conversation' about one task? For instance, can she/it find a place in Maps then understand a command like "get directions there" to refer to said place? I don't have a 4S to test myself.
It is impressive technology, but right now, my #1 thing I want Siri to do is understand me all of the time. I find the speech recognition is not as good as I had hoped, and I am frequently repeating myself and trying to enunciate more.
