Virtual Earth is a service offered by MSN that provides maps, directions and satellite images and aims in competing Goggle Earth. Virtual Earth supports easy panning and zooming; integrated aerial imagery with labels and street overlays.
However, the greatest difference between Google Earth and Virtual Earth is that the latter introduces 3D maps in a version called Virtual Earth 3D. Specifically, Virtual Earth 3D allows to browse the Earth in 3D including textured buildings for several major cities. Also note that in order to use it, first need to install Virtual Earth 3D (Beta).
