Well, had Microsoft not sold their "share" of loan to AAPL, they would have held a good chuck ~ 18.1 million shares [1]. Based off the AAPL splits, today those shares would have been 10 times more in count and 100 times more in price.

I wonder what Steve Job's net worth would have been if he never sold his shares.

When he died the greatest contribution to his net worth was his Disney money actually.

...and Disney stock has roughly tripled since he died.

He owned 13.9% of the shares post-IPO. That's equivalent to about $104B at today's prices.

And more important: I he hadn't he wouldn't have had the money to found NeXT, which was quite probably required for Apple to survive.
