The latest update of Nokia maps got rid of a few bugs and added some amazing features. The traffic updates are not only based on the national warning system (pretty standard stuff) but also use live position/speed data from other users - that is more advanced than even the most sophisticated stand alone SatNavs.
Google need to wake up to how big a selling point Nokia's 'free forever' high quality maps/nav really is. They seem hung up on maps as adding value in searches and are happy for third parties to look after nav!
I think Nokia's offering is the only thing keeping them going in the smart phone sector - symbian is very long in the tooth now. Time to put the last nail in the coffin if you ask me.
