I just saw an advert on Channel 4 about Siri that I'd never seen before. It seems to show more functionality than before. Questions such as "Where am I meeting Emily tomorrow?" (I'm re-building from memory here, not exact command). And using the "where's my buddy" app they introduced some time ago, it shows a guy at what looks like a stadium of some kind ask "Where's my brother?" And I think "Am I going to have a good time in Paris?" for the weather. The advert seemed to show more functionality than we've seen before.
