Im sure they do, but you still made it sound easy from a coding point of view. You say it's a matter of priority and economics, that may be true, but the end result is the same. More worrying i think is when you say the Opera developers want to wait to get surpassed before improving. Considering Opera's market share, and hunger for more, the idea of waiting when your not even close to being a dominant force in your field seems like the wrong road to take. I think for historical and practical reasons, browsers like Opera and Firefox will always have to work harder at capturing it's audience, then browsers that come build-in to OS's like IE. Waiting to get surpassed is one step forwards two steps back. I know from the language used both by users but more importantly developers that Firefox development is not going to rest on it's laurels, they truly believe and strive to make Firefox a dominating player. Sure it might seem unrealistic but it is a goal, a standard you might say.
