RWWeb points us to a new iPhone application called "Say Where!" That takes most of the typing out of finding driving directions. The application works by using voice recognition to decipher the point in which you want to travel. From there, it uses a plethora of tools (Google Maps, MapQuest, Ask.com, CitySearch, Yelp, and others) to give you directions to where you want to go.
It isn't yet turn by turn GPS but it is a big start - maybe Apple will have something to add to this tomorrow?. It also is nice
