For those of you that travel abroad with any kind of frequency, or have ever found yourself in a place where even the most basic english is not understood...I've read that Siri will have a very intuitive translator software that will basically make these situations nonexistent.
When me and my wife went to Italy years back, we left our tour and went on our own to several places and found ourselves unable to communicate a few times (having to search high and low for help with translation, as we only knew very basic and common italian which didn't help out in the country...
That is going to be amazing honestly...to be able to go anywhere in the world pretty much and have the phone act as a fluid translator.
