Some may know, others may not, however Google have decided to make their Pro version, which used to cost $399, free. (Once $399 A Year, Google Earth Pro Is Now Free | TechCrunch).
While many will not use Google Earth for much more than the run of the mill work, it is interesting to note that Google couldn't make this a viable commercial product, even though it is massively popular in its free version.
Cheers for now.
