I know that I am a big fan of Microsoft products and technologhy, but I read today the Safari (from Apple) is ready to download.
Despite this version is still a beta, you can download it to your PC and start playing with it.
I downloaded it just to get the feel impression of it and also to has an idea how my web applications are being showed there... (good for cross browsers suitabilities). And it's nice...
Download is here.
