I've been missing working with the Opera Browser since I went MS free a year ago. They've just released a new version for Linux which gives us yet another great web browser option. What makes Opera unique is it's usability combined with features like speed dial, widgets (HTML widgets for you desktop) and possibly the best password and RSS integration in any browser. Opera is also a bit of a throwback - it contains full email, IRC and usenet capabilities, much like browsers that trace their roots back to 1994-1997.
