Sorry, I feel sort of stupid posting this, but going to anyway.
I use Google Maps from time to time on my Droid, so I know what that is all about, no explanations needed. You can click on satellite view on Google Maps, I understand that. But, I guess since I really didn't use Google Earth on my computer much, I don't understand what Google Earth (when available on the Moto Droid with 2.1 integration, or whenever it's added shortly afterwards) is going to be different from Google Maps.
Thanks in advance.
