I haven't downloaded Safari for Windows yet, but I've been thinking about what Apple is up to. All by itself, Safari for Windows makes little sense. However, as a port test for Cocoa and Apple's libraries, it makes a lot of sense. What if Apple is getting ready for a sideways attack on Windows? Make it easier to develop applications that run on Windows and Mac in a way that is more native to the Mac? I suspect that's the game that is afoot here.
