hmmm, might have to try chrome. wait, is there chrome for Mac yet?
No Chrome for Mac, yet. I've been on the lookout for some time.
You can get on an email list if you want at http://www.google.com/chrome/intl/en/mac.html
I do use Chrome on my windows machine.
It's an excellent browser in many respects. However, it's a web browser, not an RSS reader, ftp client, email client, etc. (IE and Firefox perform some of those functions as well, Chrome doesn't.)
With that said, I'm still a big fan of Chrome. It loads quickly and seems to render pages well.
Chrome also provides a few neat features, like "Create application shortcuts" that creates a single-window, application-style icon and browser window. (Excellent with Gmail)
I have Chrome up and running on my Ubuntu machine, which is very handy. Firefox is still my primary browser there, but Chrome has supplanted Opera on that machine as my backup.
