This article is on the verge of libel.... Their marketing speech wants to push their agenda, so they talk down Nokia GPS. I've been using Ovi Maps on my N82 a LOT and it always performed very well, fast and precise.

Claiming themselves to be "operator of the world's most advanced location system" is ridicilous in itself. They use GPS and cell tower triangulation just like Nokia, then add their WiFi-Wardriving coverage which only adds 70% of the urban population in the USA/Canada and nothing else in the world. Wonder how they keep up with fast changing AP names and locations (moving, new hardware etc. etc.)
Perhaps it helps in the narrow skyscraper corridors of NYC, where you can't see a satellite but have plenty of WiFi.
