Even though Apple (NASDAQ: AAPL) reported a 31% jump in third-quarter earnings, its shares slipped on Tuesday. Many investors point to the company's conservative forecast for the fourth quarter and on concerns surrounding Steve Jobs' health. So just how important is Steve Jobs to Apple's ongoing success?

And what does the future hold for Apple as it does battle with the likes of Research In Motion (NASDAQ:RIMM) and Palm (NASDAQ:PALM)? In this installment of "Fool Video," we ask Fool contributor Tim Beyers.
