couldn't agree more on the Python example, I think one of the main agendas for the 2.0 release will be to make it more popular on mobile side of things (https://www.airport-parking-shop.co.uk/blog/built-app-2-week... is one such example though not from the core AngularJS team) for which they may have compromised backward compatibility infavour of performance.

and also do you think they'll continue with the 1.x releases? since so many developers have already invested time and effort on their webapps and shifting it to an entirely new framework (read release) is a major cost to pay..
