Right. The magic is, when you search for example, some place, Later you will be surprised your phone pushes some notifications about the weather of that place, how and how long time to get there... You don't need to tell google where you want to go or what info you need, Google Now provide all necessary or maybe-useful info to you automatically. But yes you can trigger it off. And it is not so smart as we except, kinda like AI. I hope it will be the REAL personal assistant, not just like Siri, you have to send order before it acts as smart.
