Re: Apart from the naming, how does this differ to what's already happening now?
It's pretty obvious that this will not work well in most corporate environments, especially those that have air-gapped networks. Testing patches before deploying to production machines is a best practice that is too often neglected, but it does no good to Microsoft if they force those who Do It Right (TM) to abandon its OS because it undermines their processes.
With Windows 10, the experience will evolve and get even better over time.
It might work, at least somewhat, in the home environment if the GUI is divorced from the rest of the upgrade process. I wouldn't hold my breath; they will fail to learn from either Google's mishandling of Android updates (allow the service providers to decide) or their own past mistakes and end up with a fragmented mess despite talking a good game.
