I think the point imgabe is trying to make - and I've had a similar experience - is that you occasionally receive information that _you don't even know you need to know_. For example, if I'm familiar with an area, I may have a particular gas station (or whatever) in mind, only to suddenly be given information that shows there is, in fact, a better option available to me. It's not (just) a question of saving clicks, it's the idea of giving you information off the cuff that is contextual to your situation.
Google Now sounds paper-clippy and diminishing returns to me...
