Looks like that $1 salary has finally started to pay off for Stevie J.; either he's actually immortal and has been working since before the Earth was fused together in the solar forges of the heavens, or all those backdated stock options and Apple perks really came through. Either way, according to Barron's Mr. iStuff made a big jump up from his previous estimated net worth from between 3-6 billion, and is now hovering somewhere around the 20 billion mark -- counting his estimated influence on Apple's market cap. While only Steve knows how much he's really worth, we'd like to invite him to take us out to dinner... any time Steve, seriously, we're available. And we won't even call you Mr. iStuff in person -- promise.
