I played around with Dart for a while. It is really great having a debugging console while you are working. The difficulty I had is that the popular frameworks do not target Dart so you'll always be a step behind when using Dart. I don't know if it's possible to port over a javascript framework, but I wonder what the benefit would really be. After all, you would still be using the framework's code structure. That kind of minimizes the benefit of using Dart. If they can make a nice web framework (like angular, backbone, etc) they'll find the niche that they need to fill.
