Ok, some say that opera is a bloated and slow web browser that's day is gone. Maybe that is true, but whether it will die or not, I think opera is getting the point. I tried out the 1.5 beta of opera and I liked it. By default, the menu bar is hidden and only the tab and navigation bar are there.
You can put it back, but I always liked as few toolbars as possible. And about opera's 'bloat', it makes it a maybe slow, but a reliable browser with java and flash built in.
