Woz's testimony to a WSJ reporter today isn't exactly watertight, however: he merely spoke to Jobs (On a call or in person? The WSJ doesn't say), and didn't ask him directly about the Apple CEO's health. Rather, Woz simply states that Jobs "doesn't sound like he's sick":
Apple co-founder Steve Wozniak said Steve Jobs sounds “healthy, energetic” a month before the CEO is expected to return to the company.
On the sidelines of the All Things D conference, Mr. Wozniak said Mr. Jobs “doesn’t sound like he’s sick,” nor did he seem to be in a health crisis. Mr. Wozniak said, however, he has never directly asked Mr. Jobs how he is.
Mr. Jobs, one of the highest-profile CEOs in the tech sector, went on medical leave in January, saying in a letter to employees that his health issues “are more complex than I originally thought.”
