Having lost 2 close relatives to cancer in recent years, I really wouldn't wish it on my worst enemy. The man has had to deal with pancreatic cancer a few years ago. Looking at that image, one can't help feeling that he's had a relapse and it's popped up somewhere else. I can only echo the sentiment that he makes a recovery.
Love or hate Apple, credit has to be given to Jobbs himself. He's always been passionate about technology. You only have to look at those old videos of his NeXT step demonstration days to see that.
And before anybody feels like making a cheap shot at the apple fanboys, remember that to many present-day Apple users this guy is revered in the same way we do Jay Miner.
