Been using it for almost 9 months exclusively on OSX. It works on Peter's page and just about every one I have encountered except the most stubborn .asp hacks (which wouldn't run on Explorer either).
Microsoft is obviously trying to tell Apple to "back off" with Safari (and Quicktime), but it won't work. Camino (a OSX native mozilla build) is already the best browser I have used on any platform. I have my own email program (thankyouverymuch) and web design software, so just give me a browser. S'all I want.
