> How many people can name the chairman of the board at Apple today off the top of their head (Arthur Levinson)? And how much does Arthur Levinson steer the broader direction of the company? That's just not what the role is about.

Jobs in that role would likely take a much more occasionally-active role w.r.t. future product direction since that was kind of his bread-and-butter and the company was his long-time passion project. Not because that's the regular purpose of that role, but because that's what he'd probably want to keep doing.
