There are 10,000 apps available on the iPhone App Store as of 2 days ago. Almost all of them, with the exception of some really useless ones, are revolutionary in the mobile space. However, there is one that really sticks out in its innovation; Google Earth. When Google Earth was introduced on a PC, anyone that used it was immediately blown away by the fact that you can view all parts of the globe from the comfort of your home. Now, the same experience is available on a mobile device.
