Steven over at the Anomalous Anomaly have composed nice and detailed list how the browsers score on the Acid 3 test. Results are pretty much as you'd expect them to be. Firefox 3 beta 3 doing pretty OK (69%) while the latest build of Safari for Mac OS X 10 scores nice 90%. But then it gets excited, well interesting as IE 5.5 leaves its younger brothers IE 6 and IE 7 behind not by much (2%) but leaves them behind nevertheless. Interesting, how so archaic browser could pull something like that off? Beats me
