It seems to be a common wisdom, that whatever "startup ecosystem" is in the Valley, MSFT is doing essentially the same thing, but internally, therefore it is not so visible for outsiders. My guess is AAPL is the same, only even more secretive. GOOG seems to be in the middle with the 20% working time. The basic idea is the same. But as Joel Spolsky pointed out with Jeff Attwood, it doesn't make much sense to be an "3ntrepreneur" for a corporation you have little influence on. Many leave GOOG because of this, to make it for their own benefit and control.
