I do not use Google Now that much but I've got to say that I am surprised how well it predicts what I am going to do based on patterns. First it knew all by itself where my home and where my workplace is (it named both correctly) and when I am leaving the house - then it suggested that I give that new place I am visiting more and more often a name. (my girlfriend) And then it knew before I knew it myself that I will go to my girlfriend on a monday because I've apparently been there the last 3 or 4 mondays. It's not that hard to see such a pattern if you are actively looking for it, but I wasn't really thinking that much about when I visit someone and if there is some kind of pattern. I am pretty sure that such a tool can be amazingly predictive and helpful given enough time and data.
