Here's something to stop and think about...
I have a TomTom One. It's a small, hand-held device with a set of road
maps of the whole of the UK stored in flash RAM.
I have no idea what kind of CPU powers this device, but what I can tell
you is this: When I ask it to plot a route, it can seemingly analyst
tens of thousands of roads and quickly find a suitable route. (Typically
takes less than 10 seconds.)
That doesn't *sound* very impressive... until you sit down and try to
think of a way to program such a thing yourself. How would you do that??
