As a cross-platform Google Earth addict, I've been chomping at the bit for a Mac OS X compatible version of Google Earth ever since I installed the program on my PCs.  Now, Mac users can view the virtual flyovers that Windows users have been enjoying for free for several months now.  The beta program positivley screams on a Power Mac G5 Quad, but it's also smooth on a PowerBook G4 (using default settings).  It sure is more entertaining than Google Maps.  I'll have to try it out on the new iMac when we get one in.
