For those unenlightened individuals that do not have Opera, repent and you shall be saved. Anyways, the browser is really nice and very customizable. You can disable pop-up windows (isn't that reason enough to switch) as well as mask the identity of the browser and disable referrer logging. I know the major complaint used to be "It won't display some pages.." I have never come across a single page that opera cannot display correctly. Anyways if you are interested download the bad boy here
I think it is about a 10 meg download. Enjoy.
