If it is rough around the edges now then it always will be. Witness the Firefox browser. There is a huge backlog of problems with it yet they have the resources to start something new.

I really don't get the negativity around Firefox OS or the Firefox browser. In regards to Firefox, I consider it the best browser right now; Chrome has many problems of its own and considering the resources that Google has, you'd think they would find a way to make Chrome be less of the resource hog that it is or to provide something like the awesome-bar or extensions for the Android version - and don't even get me started on iOS or Safary.
Truth of the matter is, Firefox OS directly benefits Firefox the browser, in ways that Android will never benefit Chrome - all APIs that are experimented in FxOS will make it in the browser, XUL is gone, the architecture is multi-process and better sandboxed, etc...
