I LOVE Opera 4. I am able to do things with this browser that I was unable to do before. For instance, I was out one weekend and realized that I hadn't set my fantasy football lineup. I tried with the BB browser, but it just couldn't handle the scripts and gave me the "mobile" view from which I was unable to make any changes.
Flash forward to this weekend and Opera4. I was able to make all the changes I needed without incident. I think I'm going to really like this browser.
