Thank you. If it ultimately performs as promised, yeah, it will be great. But is it worth investing your time in now in this beta-development stage? The thing that kept hitting me about dart is how fast it's being pushed, and how unfinished it is. Add to that Google's insistence that it's an amazing fix (read replacement) for doing things in javascript, and its target platforms, and I think it's obvious what the real goal is. Whether Google will succeed in pushing Dart via marketing will (in my humble opinion) determine whether programmers will want to take the time to add it to their coding-languages.
