Apple Co-Founder Steve Wozniak On Steve Jobs' Medical Leave

Apple co-founder Steve Wozniak told CNET that he was surprised to learn that Apple CEO Steve Jobs' was taking another medical leave of absence.

"The news actually frightened me because I did not expect it," Wozniak wrote in an email to CNET. "If Steve is tired and wants a bit more normal life, more power to him."

The co-founder added that as of the time he emailed CNET on Monday, he had not yet contacted Jobs.

Wozniak left Apple in 1987, though he and Apple's chief have kept in touch since Wozniak's departure.

At a conference in Spain last year, Wozniak said of his relationship with Jobs, "I chat with Steve Jobs now and then, from time to time... We have never had an argument, we have always been friends. We are not close friends like we once were spending every day together."

Apple COO Tim Cook will oversee day to day operations while Jobs is on leave.
