Let’s stop talking about the iPhone3G for a minute. Did you get a good look at Steve Jobs at the WWDC Keynote yesterday?

See the pic above: on the left, Steve at the keynote for iPhone 1.0 over a year ago, and on the right, at yesterday’s presentation. They say black mock turtlenecks really are slimming, but this is a bit much.

Ever since he came onstage yesterday at Moscone West, the web has been as much abuzz about Mr. Jobs and how frighteningly thin he’s become since we last saw him as much as the new iPhone itself. Google his name today and you’ll likely get news items like this at the top of the search list.

Jobs came out in 2003 to disclose his ongoing battle with a rare form of pancreatic cancer, which has since been successfully treated, or so he says. It’s hard to tell because, as we all know, Apple and Steve Jobs seem pretty good at keeping secrets.

If something’s amiss with The Steve, it’ll have tremendous impact on the future and direction of Apple, because face it—the man is Apple. More than any other company in recent history, multi-billion dollar Apple Inc. is the one whose fate is most intimately intertwined with the vision of its leader. Let’s hope that he’s just been spending too much time with his Wii Fit balance board thing.

Seriously though, let’s pray that things are all right for Steve Jobs.
