So glad 1.0 Final was released! Though, I cant wait for 1.1 with additional speed improvements. I've been doing some searching and found this article that Google posted.
Mobile browsers have a 300ms delay to fire the "click" event so the browser can wait to see if your double tapping. They have detailed a workaround for this so buttons wont have the 300ms delay. Just thought this might be helpful for the 1.1 speed optimization work.
