Will be quite interesting when that's ready. The leaked memo is 3 years old now, by the time Dart for Chrome is ready are the original reasons for developing the language even going to be applicable any more?

Flash, Native Client, and now DartVM, too, all being built into Chrome. Is anyone else worried that Chrome may become too bloated, and more of an "OS on top of an OS"?

I'm not as worried about the file size as I am about the future performance of the browser itself, and becoming too complex and with too many bugs because of that.

Chrome for Android has already gotten a lot of flack for being too bloated and slow (as an app) compared to the previous Android browser, which was made for mobile from day one, while Chrome for Android just seemed almost fully ported over, which I think hurt its performance on mobile, and they're still working on fixing that and optimizing it.

This. Will dart ever ship in a browser? It was one of the design goals of the language, sure, but the lack of actual end users is the thing holding Dart back in many areas. Until they make this jump, Dart is just another compile-to-js language among many.
