Ovi map is coming free to .... "The N97 mini, E72, Nokia 5800 XpressMusic and the Nokia 5800 Navigation Edition", more details here, http://www.pcworld.com/article/18733...customers.html

There is a difference between Ovi map and Android turn by turn, same report,

"... In late 2009, Google started offering a free navigation service with turn-by-turn directions with the release of the Motorola Droid and Android OS 2.0. There are a couple of differentiators between Google Navigation and Ovi Maps, however. Ovi Maps requires no network connection for navigation so you'll save your phone's battery life and not be thrown off by cellular dead zones while on the road. Ovi Maps use something called "hybrid vector maps." According to Nokia, these maps are high quality, but less data intensive so they are actually stored on your phone when you download them...."

Bottom line, Nokia's one is better............if it does come to N900, eventually
