With share repurchases and dividend payouts not helping to revive Apple's (AAPL) lagging stock price, it may be time for the tech giant to tap its sizable cash pile and buy a game-changing business to excite investors. One business that could certainly fit the bill? Electric car maker Tesla (TSLA) , which is a place that often serves as a talent pool for Apple. 'They could certainly [buy Tesla] if they wanted to, they certainly have the financial capacity to do so,' said former Apple CEO John Sculley in an interview with TheStreet, adding, 'If they chose to [buy a big company] I am sure they would only do it with a product that was intended to be revolutionary in a large addressable market -- so an automobile maker like Tesla would certainly meet that criteria.'
