Oh, good point. Mobile browsers are disproportionately Safari, so you need to filter those out. (It's not hard. A lot of them yield to a simple search for case-specific iP ;))
And then you may find that it's the mobile-ness rather than the safari-ness that's the real variable.
otoh, I am surprised at the number of people who use iPhones for sites that you wouldn't think were physically possible to view at that size.
