I think we're stuck with Schiller until Jobs decides to introduce something evolutionary.
Possibly, I think Jobs is OK for the fact he doesn't need to be on the spotlight at all times, but at the same time he might miss the fact he is not on the spotlight at all times.
Maybe after the surgery, his priorities changed and he is passing the torch or taking easy on his role at Apple. Who knows?
I would welcome though he on this special event.
