Why not use Microsoft Streets & Trips?

I have used it for years, and most of the questions I see posted here are answered by this software. Zip codes, mapping, driving distances, tracking, etc. are all features. It also has buttons for Virtual Earth views. I don't work for them, it's just a program I've used for a long time with a great deal of success.

If you want to use the program interactively, that's fine, but you cannot program Streets & Trips - that's where MapPoint comes handy.
