After the addition of pinch and zoom on the Nexus One, it is turn of the Motorola Droid to get that feature too on the same new Google map app version 3.4.0 (available on the Android Market) . The Gallery and the browser with P-A-Z capability have to wait a little longer however.
Other enhancements included in this update:
* Starred items from Google.com now sync with maps
* Search suggestions from maps include maps.Google.com search history
* Night mode navigation
