Why Google Earth and Prime Meridian Don't Line Up
One thing several people have noticed since the Google Earth application was released is that the Prime Meridian (0 degrees in Longitude) does not line up with Greenwich, England like they expect. So, if you go to Greenwich in GE, and turn on lat-lon lines by going to the menu "View->Lat/Lon Grid", you will see the Meridian line is about 100 meters east of the Greenwich observatory (viewable quite clearly in the satellite photo). This is not a mistake on Google's part. The developers of Google Earth (originally known as Keyhole) chose to support the same coordinate system as that used by GPS technology known as WGS-84 World Geodetic System. Here's an excellent post by one of the GE developers at the Google Earth Community which explains this in detail.
So, if you go to Greenwich, England with your GPS, it will in fact require you to walk about 100 meters to the east of the observatory before you will reach the GPS prime meridian. And don't believe anyone who tries to tell you Google is trying to realign the planet.
