WebKit and Opera are really scrambling to be the first browser to fully pass Acid 3. First, Opera claimed they were at 100/100 in a private build, then Ian corrected the test (based on feedback from Apple developers), presumably knocking Opera back to 99/100. And just now, the WebKit guys have turned on SVG Animation (SMIL) in their nightly builds, putting them also at 99/100. This was a surprise to me, since I had heard that their SMIL implementation was not ready for prime-time, so to speak. Oh well, this is great - now we have a second browser implementing SMIL natively and we can truly start pushing for interoperable solutions.
What does it mean for Apple and Opera fans? Probably a lot. What does it mean for web standardistas? Apple and Opera care (more?). What does this all actually mean for web developers at the moment? Not a single thing. Oh well, time to tally up my own similarly-meaningless SVG support score...
[Update 10:25 PM CST: Apple did it. They are the first to achieve 100/100 in Acid3 with a publicly downloadable browser (even if it is only for MacOS)]
