I almost never do a Google search, or any other internet based search, from my iPhone. There are specialized applications on the iPhone that are designed to grab specific types of information from the internet in a form that is friendly to the size of the iPhone screen. Thus, traditional search services on the iPhone are irrelevant for me. However, if a tablet comes out which has a browser that feels more like a desktop experience, then these search issues (Bing vs. Google vs. Apple alternative) are more relevant for such a device.
