Yeah, I've just started uding Opera 5. By far and away the fastest browser on earth. Yes, their claims are true. Also features wise it's great with an intuative (?) interface called mouse gestures were you can perform very common commands without having to use a right click menu. I still use IE for a couple of sites although this is just a few. Only other gripe is that Go!Zilla download manager doesn't intigrate with it which is a shame but it does have its own and get right works well with it although I haven't tried it yet.
