The ability to share through email or Internet geo-URLs with referenced 
image or data overlays is really great.
You need the commercial license to be able to share databases.
The very high resolution areas are obtained not from satellite data but 
from aerial flyover.  You can see the seaming in places like Tokyo from 
wide angle lense perspective of buildings.  Still great, and in some 
places like Las Vegas can give effective resolutions of 4" per pixel or 
better.  Earthviewer shows you the one or more data sets involved in 
each view as you move around, which is cool.

The price on the pro version has dropped quite a bit, from $1100-1200 
down to $600, but there are several gotta-have add on modules for $300 each.

They only have average and/or typical peak traffic information 
available, right?  Realtime information would be very cool, like Tokyo has.

Nasa WorldWind seems very very similar.  Earthviewer/Keyhole in fact do 
use the Big Blue Marble data, but the engines seem to have identical 
goals.  A history of which came first and the relationship would be
