Steve Jobs Lives!Steve Jobs Lives!

In the days following Steve Jobs' keynote at Apple's Worldwide Developers Conference in San Francisco this week, a number of online publications expressed concern that Steve Jobs was sick.

This isn't simply wild speculation brought on by lack of a world-shaking product announcement: Two years ago, Jobs underwent a successful operation to treat a rare form of pancreatic cancer.

And having attended the keynote, it did seem odd to me that a showman as accomplished as Jobs would delegate so much of the presentation time to capable but less compelling Apple speakers.

So I e-mailed Katie Cotton, Apple's VP of worldwide corporate communications, to inquire about Jobs' health.

Her response: "Steve's health is robust and we have no idea where these rumors are coming from."

(I'm just guessing here, but perhaps the Zune marketing group?)
