Let's say you're doing some web development, and it takes 100 hours. Take 100 and subtract the score, that's how many additional hours you need to spend to make sure it works on that particular browser.100 hours - IE9 score of 32 = 68 additional hours to make sure what you developed also works on IE9. We're pissed because we also have to do this for IE8, IE7, and the full fist up the ass that's IE6.Meanwhile, other browsers have perfect scores of 100. 100 hours - Safari/Chrome/Opera score of 100 = 0 additional hours to make sure it works with all of those browsers (and usually there's virtually no legacy versions that require supporting).I really wish Microsoft would just give up and use WebKit already.Now, if you're wondering what Acid3 means to you as a user of IE. It doesn't matter, except to know that the browser you're using is lowering the quality of almost every website you visit because the developers had to design with IE being the lowest common denominator, and all the resources being consumed to develop for all the versions of it.
