Apple Safari for Windows

I am surprised: Safari for Windows :-)

I just installed the new Safari beta 3 on my MacBook, but did not grab the Windows version. I see the big win distributing a Windows version of iTunes, but I don't see the win for tossing another web browser into the mix available for Windows unless Apple is planning on making Safari into a platform with "proprietary" extensions. I quoted "proprietary" because the core of Safari is open source.
