I have been reading a lot of confusion about multitouch support in Android 2.0 so I wanted to clear things up. Android 2.0 has full support for multitouch. You can read about the developer APIs on the official Android site.
The Motorola Droid has multitouch capabilities, but several reviewers noted that it did not include pinch zoom in the browser so they incorrectly claimed it lacked multitouch. The Droid does feature in fact feature multitouch when using the soft keyboard and it will also support multitouch apps and games that are designed for it.
It would appear that Google left out pinch zoom from the browser because of the Apple trademark.
