Well I dunno, I recently seen Woz do some TV interviews and he sounded like a good speaker to me. But TV is different from standing on a live stage, so that I dunno ?

He's a horrible speaker, and is somewhat out of touch with reality.

Well Steve had that Reality Distortion Field working laugh Woz certainly is not a visionary but I can see him as promotional, maybe a few TV commercials, maybe as a keynote host ?

I hate to say it but to me , Tim Cook sucks at public speaking - Don't get me wrong he is a good speaker , just he is very monotone , no emotion , lacks the ability to really kick punch lines like Steve did. I think this is where the Woz could be beneficial as a keynote host , introducing the other Apple VP's demos. Really anyone would be better than Cook when it comes to Facilitating.
