There was some rumors some weeks back that Apple was going to release Safari on Windows. I didn’t pay any attention to it then, but it struck me the other day that it’s quite likely. Perhaps not Apple releasing Safari, but someone releasing a WebKit-based browser for Windows — because really, Safari is more or less just a shell on top of WebKit.
I can even give you a when: as soon as Adobe releases Apollo.
Apollo will be built on top of WebKit, so WebKit has already been ported to Windows (which couldn’t be very hard, since it came from KDE to start with) and writing a fancy web browser UI in Apollo should be easy as cake.
We’ll be seeing Safari on Windows very soon.
