When Apple and Google (GOOGL 0.55%) squared off over which had the better map software, a new battleground in technology was created. Apple's missteps in the arena remain some of the most discussed mistakes ever made by Cupertino. Even today, the relationship between the two behemoths remains strained over this very subject.

In the video below, Fool.com contributor Doug Ehrman discusses the reasons that maps have become so central to the battle for the top spot in tech and where the latest news leaves the big players.
