I just wish that more people would promote it. It's so nifty. You can even download Opera mini to your handheld PC or phone and have all the function and capability on the go.
My favorite part is the mouse gestures. Just a movement of the mouse can let you do whatever you need. The newest version even has a 'speed dial' so your favorite websites are just a number away. Ooh! Plus! It has an AWESOME feature that detects when something is in a series (like clicking 'next' in a gallery of pictures) and allows you to just hold the left mouse button and then right-click to move forward. Just hold the right and then left-click to move back.
