If you have a look at the Macintosh Headquarters in America on Google you will see that the building is there but if you try to find it on the Microsoft version you will not have much luck as they have covered it over with a field.
The same is for Area 51. On the version that I saw Micosoft Covers It Up with Teal Boxes but Google once again shows all.
The third thing that I have noticed is that Google Earth shows all the Military Bases around the world but the Microsoft one covers them up.
I'll try and find examples for this, I haven't used the programs in a while.
