The "jogging guy" portion of the video shows Siri juggling context to a surprising degree. I think there's a pretty clear line between that and voice search + instant actions.

It's not unlike the line between what Google does and what Wolfram Alpha does.

I interpreted the parent's comment as being about things like "great Greek restaurant in Cupertino", which are essentially instant search.

but yeah, the reminders stuff in particular is a cool new realm for voice control.
