|"MSFT... can return all the investors' money in less than 30 years with almost no growth"|
They could. But they won't. Instead, they will squander it on "strategic investments" in innovative new technologies which they will then destroy to prevent them from threatening their entrenched Windows/Office monopoly. And they will waste it trying to forcibly push losers like WinCE, MSN, and Dot-Net in order to illegally leverage their Windows/Office monopoly.
In contrast, AAPL could return investor's money in a long weekend by liquidating their short-term investments and auctioning off their intellectual properties. But they won't. Like MSFT, they are on a Holy Mission, and they won't rest until they have conquered or been defeated.
"You may choose to not have an optimistic view of the world, I do."
Predicting MSFT's demise IS optimistic.
