Appleinsider report that the Mac OS X port of Google Earth is on the way.. Seems to be a straight port of the windows version, although the claims made by Appleinsider that the imagery will be improved, must be false.

The imagery appears to be idential everywhere I’ve looked. Perhaps the reviewer is getting confused by recent improvements – for example, how much better UK imagery and placemark handling are.
