Steve Jobs, the former Apple CEO, has died at the age of 56 at his home in California.

He resigned recently citing health reasons and was replaced by Tim Cook.

Whatever anyone thinks of Apple, or of Steve Jobs, he and Wozniak flipped the IT landscape on its head, again and again.

Jobs had been struggling with pancreatic cancer. He is survived by his wife, Laurene, and four children.

Apple's website displays an image of Jobs, 1955-2011.
