Looks like Google is finally officially enabling multi-touch on the Nexus One in the US. Hopefully this is a sign that whenever 2.1 hits for the Droid it will include multi-touch (and heck, while we're hoping let's pray for flash support!).
I've never felt a huge need for pinch zooming (since a double tap is more efficient usually) but after using the Milestone browser for a while I can say it's nice to have the option when you need to zoom in more precisely. And it would be very helpful in Google maps, because sometimes the default zoom options aren't quite right.
