A few years ago, when Apple slotted one of the most important pieces of their puzzle firmly into place, they used the line "Hell Froze Over". They were talking, of course, about the release of iTunes for Windows; a software release which arguably set the course for Apple's future endeavors - the huge success of the iPod, the "Switcher" phenomenon, PC Guy vs Mac Guy, and more.

I firmly doubt that Apple would be where they are today, were it not for the historic decision to port iTunes to the Microsoft platform. And they've done it again: Safari has been ported to Windows in the apparent hope that it will mean a greater market share for the browser. It worked before, it might work again.

But Apple's real plan is surely twofold. Firstly, and most obviously, they want to give people a sniff of the sweet Apple scent that's proved so tempting. Windows users can now sample iTunes (an application the Steve Jobs recently said was "many people's favourite application on Windows") along with Safari, and the ever faithful Quicktime. Apple, and Jobs, have proved that iTunes can tempt people away from Windows; time will tell if Safari can achieve the same thing.

The second reason for Apple's release of their browser for Windows is likely to be the iPhone. Jobs' WWDC keynote covered three things: Leopard's new features, Safari for Windows, and the iPhone's support for "Ajax and Web 2.0" as its means of extensibility. If the iPhone's version of Safari really is the same as its desktop counterpart, then releasing Safari for Windows essentially provides both Windows and OS X users with the means to create Javascript based applications that should function on the iPhone. Again, time will tell as to how successful this move will be.

How does Safari fare on Windows? See for yourself. It's fast - although perhaps not as fast as Apple would have you believe; pretty - in a minimalist kind of way; and will be instantly familiar to anyone who's used Safari before. It's also a little memory hungry (after a brief browsing session it was cheerfully consuming 200mb on my machine), doesn't support the "back" button on my mouse, and won't let me use control + enter to add "www" and ".com" to a url in the address bar; clearly a little adjustment is needed, but it would be nice if Apple made the transition slightly easier for Windows users. Also, there's no introduction or help screen to point out the "unique" features that Safari offers: you're very much left to your own devices.
