Microsoft is rolling out its new "version 2" 3D imagery in four cities (Las Vegas, Denver, Dallas, and Phoenix) for now, with more to come later. The rest of us will have to wait and look on in envy. 3D improvements include higher-resolution textures, rendered trees, and buildings reaching farther out of the city cores and into the suburbs.
The Live Maps team is really together right now. It is offering a product that, in my opinion, is clearly superior to Google Maps. Live Maps is the best browser-based map experience out there today.
