A friend had Streets and Trips along on a recent business trip in which we had to drive, and the thing was a nightmare.

At one point, it changed our destination by 30 miles for no reason whatsoever (but still claimed it was our destination). Basically, it said the equivalent of take I-90/94 S to downtown Chicago and arrive at your destination MKE.

Even when it did work, it was impossibly detailed. Making a simple exit from a freeway took 8 lines of directions that all involved driving 0.0 miles. IT made it very difficult to get an overview of where you were headed and to know when your next REAL action point was, because it was buried in several non-action points.

Finally, it gave weird directions, like sending us down an alley to get to our hotel instead of turning on the perfectly good major street before the alley.

It was very difficult to use, and I give it a huge thumbs down relative to the functionality you see from a mapquest.
