Updates to Google Earth are always fascinating, but sometimes, that’s all they are; there aren’t any obvious practical benefits.  The latest update should be pretty useful, though, as Google has added roads and business listings in a number of countries, and also updated its Transit symbols.

It’s fun to “ooh” and “aah” over Google’s most interesting products and services, but it’s also frustrating to note their limited availability.  Street View, for example, doesn’t picture a road within 600 miles of my home.  But Google Transit has just added coverage in a handful of areas.
