Scrolling Google Maps like elements: Doesn't the iPhone use a two finger scroll for this? Only seeing drop down menus and interface elements when you hover over them: Make them respond to a click as well as a hover. (and I think Facebook does this already, I certainly remember having to click to get the log out link) I think that's all the objections answered. Did I miss anything?
