How would your opinion change if Dart was just a cross-compiler to JS like GWT or CoffeeScript?
And if you have no problem with that, then why is there a problem with a Dart VM in Chrome? All it means is that potentially, Chrome apps will startup faster or run a little faster.
However, this is not really much difference than V8 vs other JS VMs. There was a time when V8 was way way faster than other JS VMs, so the same speed differential existed anyway.
There's a difference between "doesn't run" and "runs, but faster"
