Your question about the importance of developing Safari for Windows given that Chrome was in the works is interesting for this discussion, but your comments afterward seem out of place since they are about Safari as a whole.
I don't see how the existence of Chrome has any relevance to the creation of Safari as a whole. First, the timing might be off (I'll leave this for others to research.) More importantly, although I don't know exactly what the point of Safari was (presumably Apple wanted to have their own browser to include with the OS just like Microsoft did), I would have to think that if Chrome would satisfy that need then the latest Mozilla browser would have as well.
