Opera had quite a bit of potential at one time; however, with the introduction of version 6, they've really dropped the ball. It takes too long to start, too long to load a webpage, and the layout of the U/I is just horrendous. I'de sooner take whatever the "pay to port" price tag is and apply it to Voyager and/or Ibrowse.
Now that is my opinion alone, and has nothing to do with anyone else. Yet, with that said, any and all browsers for our platform(s) need serious upgrades. Of that, there is no question. In other words, I wouldn't turn my nose up at an Opera port if it were available now, but I am also not going to cry if Opera goes out of business either.
