Brilliant, as usual. Looks like it's going to be an awesome interface. This is still the beta version. I notice there's not zoom yet (they say it will just be a slider bar in the window). But just the ability to drag the map around is fantastic enough! And the directions are cool, click on a step and it pops up a little magnified window of the turn/onramp/interchange. Take that Mapquest!
