There are several products with the name "MapPoint".

MapPoint 2004 North American Maps
MapPoint 2004 European Maps
These cost around $200-$300.

There is also a MapPoint Web Server (formerly MapPoint .NET). This one starts at around $8k but you can get a free 1-year trial account through MSDN.

Finally, there is a relatively new product called MapPoint Location Server, this retrieve real-time lat/lon from a mobile carrier's network (i.e. a mobile phone). See the link above for a special issue from MP2K Magazine, the MapPoint technology portal.
