"Great, Fast, Easy to use"
Opera is very fast, similar in speed to Firefox and sometimes is even faster. One of Opera's best features is the mouse Gestures, which make browsing even easier. And all toolbars are fully customizable.
There are some compatibility issues with several sites, including CNET, YouTube, and MetaCafe (nothing too big, though). Other than that, there really weren't a whole lot of problems.
