My 2 Cents on MapPoint
Brendan Tompkins praises MapPoint Web Services; I like the product too, but I'm not sure about the price point (our usage is small enough right now that our MSFT partner status lets us use it for free). We'll have to see how that shakes out. The functionality is outstanding.
There's a MapPoint blog available, too. It's got lots of tips for MapPointers out there.
