Mappoint did a lot more than Bing does... And the VPs who think Bing is the answer have no idea.
Mappoint is closer to ArcGIS than it is a consumer mapping applications. It had an extensive set of APIs that you could allow apps to push data onto maps, it allowed statistical queries and it allowed complex boundaries. etc... all back in 2004. Heck, they even had some traffic data built in for their analysis.
I remember when Verizon used on-site Mappoint servers to allow dispatchers to use Verizon phones as tacklers (this was before smartphones), so dispatchers could see where certain trucks were, directions they were going, etc.
