The 900 is a lousy navigational tool compared to its iPhone and Android rivals. Microsoft's Maps app leaves out the transit directions of its Bing Maps site and has no answer to the bicycling directions in Google's Android software. (Microsoft unintentionally advertised that omission at WP7's October 2010 launch, which took place in a Manhattan studio two blocks from 9th Avenue's separated bike lanes.)
Nokia tried to compensate by bundling separate Maps, Drive and Transit apps. Each is a mess in its own way. Maps will only let you request directions from your current location. Transit's ignorance of the bus system in Washington generated directions to Dulles International Airport that involved walking about 15 miles. Drive offered dreamily optimistic arrival times -- as in, going 11 miles through Washington's Virginia suburbs in 18 minutes.
