Exactly. Many people freak out when Jobs is away, but Cook + team (ie. Forstall, Mansfield, Johnson) proved themselves last time Jobs was away for an extended period of time.
I'd always be interested to know who would run the company if Jobs stepped down (he'd probably stay until he couldn't, given his drive) - my bet would be Ive.
I think they would mimic the current situation with Cook running the company and Ive doing the product development. What their actual titles would be is anyones guess. Cook's lieutenants are going to be very important.
I hope this is just the effects of the transplant per the NYT article. It would make sense given the compensastion they are giving Cook.
