The day Gates declared a dividend and moved on to being exclusively the chairman (and appointed "Monkey Boy" to guard his fortune) is the day your investmet changed from growth to dead money. It will never change now and the problem isn't Monkey Boy. Moneky Boy will NEVER leave voluntarily and there is only one guy with the HP to fire him. And he won't.
Ballmer is not there to grow the company, he's there to guard the company.
