Google maps sucked when it first came out. It will be fixed and both applications will improve. I think this is will only turn out two awesome map applications rather than just relying on google for everything.
Really? I remember when I first used Google Maps coming from being a Map Quest user, I was blown away that I could scroll without having to refresh the page.
I remember something very similar - I wasn't even a Google fan then and I remember just not wanting to go back to Mapquest after having seen Google Maps.
