samer wroteWith respect to HTML 5 – According to
this wikipedia article, it seems 9.0 only added audio and video tags support. Also, Trident went from a 20/100 to a 55/100 on the Acid3 test. A decent rendering engine like WebKit has had 100/100 for quite a while now.
Chrome and Opera 10 both score 100/100, Firefox 3.5 is at 93/1000, I'm guessing Safari shoudl be around 100 too. Yet IE still brags about its 55/100.
Sure the acid test is not the only factor when choosing a browser, but this shows how much Microsoft cars about international standards...
