Adding a important note:

I am aware that I can get android L via the many other methods, but you would not expect that from a individual from non-technical grounds like a doctor or a lawyer. you would not expect them to spend lots of time surfing the web trying to update Android L.

I am talking about the traditional way Google provides android updates, directly into the phone. What is up with ROLLOUT ? Why doesn't all the google device get the update at the same time.
