I have download Safari browser 3 beta version for windows for a try.
The only thing it surprise me is, Apple make it available on windows. It seems like running very slow on windows, if it is the only browser that you prefer to use, I bet you will switch to Mac OS X. It doesn't seem that slow when running on Mac OS X.
Someone (and more than one) founds security issue on it, so I just try for while and remove it.
