It all depends on functionality and performance, and how the Jolla phone behaves. If the UI don't flow with the application its not really needed. Let's say you could run Android apps on n9 via acl. That would be a waste since n9 lacks the Android application buttons, installation procedures is also something. And of course, the legal aspects.

This is just three issues realeted to using Android apps. If this acl working so great and jolla is serious of building an ecosystem on Android apps, then their phone must be able to work as an Android phone. If there are any limitations. It won't work and a native Android device is a much better option for buyer.
