Meyers and management isn't going to let anyone do that if they can help it. Just like how last time the management didn't let anyone do it.

THAT is why the core business is worth negative 5 billion dollars. Because management will do everything to drive the company into the ground in order to prevent themselves from loosing control.
Microsoft and others don't seem to know what they are doing.
