Why would Apple take Safari to Windows?

As most of you know, Apple released a beta version of their Safari web browser for the Windows platform today. It took Dave Maynor and the Errata Security guys (among others) just a few minutes to find the first security flaws in the program. Not getting into the whole why don't they report them to Apple first thing (you can ask the Errata guys about their disclosure policy on this), I had to ask myself why would Apple open themselves up to this.  Did they want to take some market share from Microsoft's Internet Explorer as this article suggests? I don't think so.  Sort of why did they do iTunes for Windows.  To take on Windows Media Player? Not!  It was a means of allowing people to use iPods.

Safari for Windows is all about the iPhone.  Apple is not going to let people develop 3rd party apps for the phone.  However, the phone will run Safari.  So if you develop Safari specific web applications, you can get them on the iPhone, assuming they lend themselves to a mobile platform. You may have to configure, install, download, etc. from your regular computer and sync with your iPhone.  Safari will be the iTunes to the iPhone's iPod.  This has nothing to do with Apple trying to take market share from IE or starting a new browser war.

Now whether it is secure is another question.  Another question is what has Apple done that so many security researchers will not share disclosure information with them.  I think they need to reassess their relationship with the security industry.
