No matter what you consider routing, navigation, whatnot, the device: * lacks the ability to natively preload an area for later routing * lacks searching capability * because of the above, any unplanned, free routes are not realizable. As a result, the device is not independent, not free and does not route unless under specific circumstances which can safely be considered outside normal operation.
If Nokia would have allowed me to preload the maps for an arbitrary area, say, Bucharest, I'd be half-happy. Forget voice. I wouldn't be happy, because I consider saved bookmarks a basic feature, but what the heck, it would drive me back home.
