I would add a few cons to the list (I agree with all the pros): - Testing can still be improved in my opinion, there's no mutation testing yet and it's still pretty verbose. If you are coming from the JS world, that's clearly superior, if you are coming from the Ruby world however, you will be disappointed a little bit on that level. - I really don't like the navigation system, it's pretty hard to know the current route and you have to go out of your way if you need to interact with the current route dynamically. - Webviews are kind-of alpha, which means no tab support, that's a killer for any kind of oauth using webviews.
