David Einhorn is a fund manager at Greenlight Capital, and he's leading the charge with a lawsuit against Apple, claiming that the company hasn't done enough to make sure its shareholders receive the benefits of their success. Apple's been making plenty of money lately, of course, but Einhorn's problem isn't with the making, it's with what Apple is doing with that money. The company from Cupertino has built up a cash bank of nearly $100 billion, and investors have already made it clear they're not happy that Apple hasn't turned that money back into bonuses for shareholders.
