The Tab Expose would be nice and fullscreen browsing is very nicely done but other than that ... I'll stick to Safari. One thing I really don't like is the fact that you can't disable the status bar (at the bottom of the window). That's one of the things I like most about Safari. And Page Tabs just don't cut it. Its a good idea just not polished. I mean, why would I want to take up more screen space? Not everyone has a huge display (12" PowerBook here), and yes, I realize you can't disable it.
