Conversly, how is Audya a finished product?

Think of it, the upgrades(?) are in single digits...OS1, OS2 OS3...etc.

Most products with OS upgrades are incremental...OS1, OS1.1, OS1.12...etc.

What makes you think it is finished?

Finished means..."brought to the desired final state."

Is the Audya in it's "final state"?

I hope not.
