This is pretty cool! Being able to use Dart easily and comfortable will go a long way I think.<p>Especially with new things like the Flutter toolkit for mobile apps, it'll be nice to have something like StageXL for porting those games to browser or from the browser to apps, etc.<p>Dart gives me the feeling that it'll be easy to port my code to another platform later. Nice and simple, but plenty fast enough and with good lang features.<p>I'm on a Chromebook, and none of the performance demos seem to work... nothing renders or happens at all
