Today, I've tried the 64-bit version of IE 7 on (also 64-Bit) Vista Ultimate on my Mac Pro. I didn't use a stop watch, but it loads an (encrypted) Internet banking page about three times faster than 32-Bit IE7 and about four times faster than 32-Bit Firefox 3. Since Firefox 3 already is a bit faster than Safari, that leaves the Apple browser on the last rank.

Furthermore, in my experience, Safari still renders many webpages wrong and some web shops don't work with it at all. Even eBay is still a pain in the neck to use with Safari, especially when you put a sale online.

And in the office world, there still is no way around Internet Explorer - too many corporate Intranet applications are not compatible with anything else.

And before you ask or flame: I mostly use Safari, for the same reason most people on Windows use Internet Explorer - it's the default, pre-installed browser, it most of the time does the job and so there's not much reason to play with something else. I usually only use Firefox when a page does not work properly with Safari.

Oh, and I don't like Opera and plainly -hate- tabbed browsing. ;)
 
Safari isn't perfect but I love it. I have grown very comfortable with it and have been using it as my main browser since it was in beta.
