I really don't understand why they don't just enable it in the US. Blah blah patent issues blah blah, doesn't stop HTC, Microsoft (HD2), Palm, or anyone else, why does it stop Google? Do they have a backroom contract with Apple they aren't telling us about? Doesn't seem like a lucrative idea, especially with rumors swirling that Apple will be replacing Google with Bing on the iPhone.
Of course, I personally hate pinch-to-zoom, when I had a Pre I still used double tap, but if the masses want it....just add it already!
