I am quite happy that one year later Android N only managed to acquire 9% and KitKat is still rocking with 18%.
Maybe now that Google sees no one gets their new shinny OS every single year, they change their attitude.
Trello is not the solution as it is only available in Android O, it still leaves to the OEMs the choice to actually make it work and with Android N at 9% one year later, who knows how many years it will take until Android O becomes relevant at all.
