I've been using the Opera on my n900 as default browser since it came out. Compared to microb it seems to be a little slower to load pages. Earlier with pr1.1 microb was much faster to start but now with pr1.2 it seems they are both equally slow. The only this that really bugs me is the zooming. If I had more control over pages are zoomed opera would be absolutely fantastic. At the moment it seems your're always too far or too close. Nokia should take an example how portrait mode should be done. The microb portrait support in PR1.2 is still a bit of a joke.
