I have no idea how close the chrome/chromium and the angular dev teams are but this is clearly a great synergy.

This is an interesting time for the browser / web framework duo, I wonder what would happen if chrome/angular become really faster but anotherBrowser/angular ends up having poor performance due to chrome specific features. Will developers turn to a more evenly supported framework to avoid performance issue or will the other browsers be forced to ensure good performance to avoid being considered as "slow" because of angular apps ?
