A large number of people have iPhones, relative to other phones on which web browsing is usable. Also, the iPhone is the first phone worth using for browsing the web, for many people.

I don't recall see this functionality in my one previous 'smart phone' (a Treo 650), but perhaps my memory has failed me.
