How predictable are you?

Ars Technica has posted about research that has been conducted about prediction your location, based upon data gathered from mobile phone towers.  The research shows that it is possible to predict where you will be at any given time with 93% accuracy, even before additional information such as calendars is taken into consideration.  That is spectacularly good, and just goes to show how good the information that is being gathered by our gadgets really is.  What this article makes me think about is how well adaptive user interfaces, once provided with the appropriate data, will be.  I want it... now.
