I think you're right, Miles; eventually it will of course be their best operating system so far - which is why I for the first time ever was maneuvering to be first in line.
BUT the comparison in my head is the car company launching a new model, and when people ask why there are no passenger seats, or why this or that obviously is missing, the answer is something like "Oh, we will add them eventually". Setting a fixed date for launching a new model is by itself foolish, or what the proper term may be, because it makes a date become more important than fixing errors, and therefore also puts a date above both the customer and the company's trustworthiness / credibility / reliability / integration / honour / something ...
Well, I am the poor one, and they are the ga$illionaires, so who am I to speak.
