Thanks for sharing. I agree that site is very slick on my iPhone 4S. When I tested this on a new Android 4.0 phone it was still pretty good, but a few things didn't work smoothly and on a 2.3 Android phone, scrolling was pretty unresponsive because of the JS-based scrolling. An approach like this is great if you only want to address a single platform like iOS but the techniques used here wouldn't work cross-platform with much performance so there is a tradeoff. Good stuff though, looks like it's built with custom jQuery code and iScroll if people are curious.
