I can see the value for a corporation in keeping more than a billion dollars in capital and assets, but not for a single person. I imagine this is why Bill Gates started giving tons of money to charities. At that level (billions, plural), what use could it possibly serve other than to pile it all in cash and gaze balefully down from your cash-throne at the peasants beneath you?

Had he been able to assuredly predict the future of AAPL (or any stock, for that matter), he'd be a hell of a lot richer than $13 billion.
