This was an obvious step. Adobe has had to port WebKit to Windows for Apollo^H^H^H^H^H^H AIR. Apple had to port some of it for iTunes. The important piece here is WebKit (not Safari). The WebKit nightlies are insanely fast. I can't wait to hear how they run on Windows.

I am not sure exactly which target demographic will be running Safari on Windows though..... and of course, it means that we have yet another browser to support (although I am sure the windows version won't have any bugs different from the Mac version).
