As much as I would like to see Steve return to the helm at Apple, I think it's fairly obvious that everyone is not being told the whole story ... and rightly so, because it's Steve Job's business and no-one else's. Sure, you could argue that Shareholders have a right to know, but if the man is seriously ill then we should respect his privacy.
I don't think Steve is terminally ill, but I do hope he someday takes his place on stage to tell us there's "Just one more thing" a few times more yet.
