I think we now know why Google hired the lead Firefox developer. Take a look at Google Maps to get an appreciation for what Google is accomplishing in the web browser. This is not your average MapQuest or Yahoo! Maps. This is a real step ahead.
Google Maps supports dragging and is incredibly fast. The ability to interactively move a map around on a screen without waiting for a page refresh makes this tool a pleasure to use. I’d like to see the addition of a waypoint feature, where I could map a route and click to add waypoints. That’d be great for supporting my motorcycling habit — it’d be a big help for designing routes for group rides.
