True, I agree completely with morbias. If there were no devs on XDA etc we would be doomed. For me it feels like 5.X was meant as a major test for ART 1.0, it wasn't yet fully implemented 😉 Curious what "M" will offer.

THANKS GOD FOR XDA. phew it had to be said loud, when i had Galaxy S3 the device was so SLOW with stock touchwiz, thanks to them i use clean android 4.4.4 and i felt like i got a new phone. now i'm using CloudyG3 on mine G3, tbh LG stock rom is nice.

The new versions of android are not relevant to most, since they not getting the update, whetever it takes years or just stops. Google need to make updating UNIFIED, we the users most choose wherever to update or not, not the opposite.

To unify it they must close a lot of the OS, which will not go well with OEMs :/

so accelerate the process, the far end Android versions are not common. It is wise idea to spread it across as many devices as possible, google can help at least major manufactures to accelerate it, if that won't happen it does not matter what google announce, few people gonna get it on time, if any.
