It was mentioned back in April actually!

I use it a bit, but I have found that the mapping isn't all that good in practice. The problem is that to see the street names you have to zoom in so far that you only cover a very small area. Zoom out to a useful size and the detail goes.
I still use MultiMap for street level mapping, and AutoRoute for route planning.
