Google Earth 4.3 (beta) is ready for downloading. I’ve played with it for just a split-second and am impressed with the improved graphics (at least from what I can see). The new features being promoted on the Google Earth site are:
Photo-realistic buildings from cities around the world
Dawn to dusk views with the Sunlight feature
Swoop navigation from outer space to street-level
If you’re a Google Earth fan, and I don’t know many who aren’t once they see it in action, then the beta’s worth a peak. I will say I have no idea what bugs you may run into, so be careful. But if you have plenty of memory and hard disk space for a nice toy you may want to give it a shot.
