This is great, and looks so much easier (as does Scaloid), but I have never found a commercial project that I can use it on. #1 by choosing Anko or Scaloid you are isolating future developers to only those familiar to Anko or Scaloid OR those willing to learn (as well as the fact that Scaloid doesn't sell very well on resumes IMO; my guess is the same for Anko).

It's a dilemma, as Java+XML is very verbose. still, with the amount of work Android Studio does, I'm not sure its a big problem for most of us Android Developers.
