This kept happening on my road trip. I would ask about nearby Starbucks so I could get online and my Droid would tell me about locations that were either off my path or where I had come from. 

So it's not just a matter of where I am, it's where I'm going.  

Location-awareness leads to vector-awareness. 

I know where you are and I know where you're going.  

Don't tell me about Starbucks that are west of here if I'm headed east.
