I installed the free public release today and played for a couple of hours. Seems very fast and is supposed to be more secure than IE or FF. However, Roboform doesn't support it yet, so it'll be backup for now. Check it out here:

I gave it a shot too, but I'm not to thrilled about tabbed browsing. Also I don't like the way the bookmarks are set up.

Just me but for now I'll stick with firefox 3.
