Safari *has* moved up. And a lot of people (including Apple fanboys) are *not* happy with how Apple abused what was nominally a software updater bundled with iTunes as a conduit to installing Safari. It was a dirty tactic to grab marketshare. That said, a lot more people now are possibly using it, and the reviews of the Windows version are considerably more vaforable than the beta windows version that was out. And of course, it is one of the dominant browsers on the Mac OS side. Hopefully, being as standards compliant as it is, you shouldn't need to expend much effort on it.
