They haven't released Safari for windows for many, many years but I think there still are Webkit browsers for Windows - although I'm not entirely sure whether that is still the case since Google decided to fork Webkit into their own rendering engine a few years ago. I know Opera uses the same rendering engine as Chrome now so you might have issues there as well, although I'm not entirely sure.
I use Safari on Mac for most things and have Chrome for annoying sites that require Flash (thankfully less than in the past since lots of online video is now HTML5), while on my Windows PC I use to play games on Chrome is the only browser I have: I haven't even bothered to stick Firefox on it. Both seem to work and Safari is very fast which is what I like over anything else.
Boring Web Browser news: the only places that IE seems to still be the biggest browser are Japan, South Korea, Liechtenstein, and lots of wee tiny Islands like Bermuda and the Falklands. Germany remains the last bastion of Firefox in Europe, Cuba seems to be the only North American country that hasn't given in to Google quite yet and large parts of Central Africa love Opera (I imagine that's because its an online browser than runs on more devices than anything else including some incredibly old things), while the most popular browser is India is something called "UC Browser" that I haven't heard of; which is apparently popular in Mali as well!
