Wow, I have to say that is just a foreign concept to me. Where I live the service is incredibly unreliable. I can be sitting in my driveway in the city and not be able to access anything. Changing the scale on a map usually means waiting 10-20 seconds for the map to be redrawn. If it even loads entirely. Streaming music sometimes works, sometimes you have to wait 10 seconds... or a couple of minutes... before it connects and downloads the next song.
It's great when it works, but it rarely works. I live in Victoria, BC. I suspect it might be roaming to the U.S. (across the strait of Juan de Fuca)
