It's not hard to love Google Earth
: it's free, it gives great views of one of our top five favorite planets ever, and it's free. Now Google is adding in some new functionality to push the realism to the limit in Google Earth 6. Most importantly, Street View is getting seamless integration into your virtual travels, with the little yellow Pegman set right next to the navigation controls for placing any which where. Google has also "planted" millions of 3D trees to make the 3D building view a bit more realistic, and has a new easy-access method for pulling up historical imagery. It all sounds very exciting in theory, but the best part? Google Earth 6 is free
, and you can download it right now to find out for yourself.
