It's got noticeably better performance than Firefox for Android (on a N7, using [0] as a "benchmark"); but Chrome doesn't seem to have audio support.
EDIT: hm, Chrome doesn't seem to want to grab the audio at all; on both the pages I've tried, the audio downloads just hang as "Pending" in the inspector [1] [2]
The HN title is misleading. It is still not enabled by default, it just got easier to manually switch on, so it wasn't "added". Still, this is good progress.
Well I wouldn't to see in Nokia's devices anymore anytime. Also these have all been just experiments. Even Apple has implemented part of WebGl in the iOS browser I think. But if Chrome beta has it, then the next stable version should have it, too.
Are you using a Nexus device? I don't think they replaced the browser on Nexus devices older than Nexus 7. Only new devices that have been launched after June last year with Android 4.1 on board should have it by default, and as I said most manufacturers have probably left the other browser in there even on new devices. But the new Nexus/Motorola devices should have it.
