I've recently got an invitation to the new Google Maps.
The slick new interface allows you (among others ) to zoom way out and see the earth.
More than just some Google Earth features that were implemented,
the entire interface is definitely more Social oriented,
you can got photos of the places you're looking at a lot easier.

The map is definitely more dynamic, showing only things you're looking for.
Directions have improved a lot, they now include Flying, and Public Transportation gives a lot more information:

oh, so that's how you get from NY to SF, I was looking forward to a 44 hour drive

The search results are a lot easier to sift through, Street View, Inside Look (street view INSIDE!), and Pictures are available without getting into a separate page.

Good on ya, San Francisco!

And after all, this slick new design means nothing if you can't watch the Sun setting on the Earth (live, kinda)

Might need some sunglasses to view this image.
