Cool.

What's an "intelligent decision"?

I'm afraid I can't provide a definitive definition, I'm not even sure if there are one that everybody would readily agree upon. But what I had in mind was an understanding of intentions or meaning from context rather than having to explicitly be told what to do.

"You insist that there is something a machine cannot do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that!" John von Neumann, 1948

I'm not sure what your point is, I gave my opinion of when a system of this kind could be said to have AI.

wether or not you think it constitutes "artificial intelligence", i think it would be silly to argue that siri was not making "intelligent decisions".
