I don't get it... Steve raises Apple from the dead, creates a whole new genre of movies (3D animation) and continues to innovate. Woz quit while he was ahead, shouts from the sidelines, and everyone listens to him?
I guess the keyword is "listen to" and not "agree with" or "follow". While most smart people are worth listening to, most may not be worth following (either because they're evil or narrowly focused or some other reason).
While it's true that Woz isn't doing much of anything right now, he's at least voicing opinions that are widely held and he represents "the old Apple" (that is, whatever Apple should become).
Woz is always so critical, at least in part, because it helps consumers trust the company. Having the second co-founder "on the side of the consumer" helps to build that bond between the tech-savvy apple fanboys, and the company itself. I don't mean to say that what he says isn't sincere, but rather, that highlighting these things and making them public does wonders for the company...and yes, he still cares for the well-being of Apple.
I don't see HIM building anything.
