Fennec - firefox in mobile

Fennec is the Firefox web browser available in mobile. It is currently on alpa version phase only. Seriously I'm not a PDA phone user (Too expansive for me), so I doesn't know how great it was. From the demo video, I saw the interface is standard and professional (similar feeling like Opera). I also saw there is some thing similar to it big brother and add-on tab in the option, I doesn't know is it finalize, if it can have the cold and useful add-on, it should be popular. How many PDA phone developer want to include Fennec remain the biggest problem.
