Re: Is Woz available?
Well, yes and no. I have a lot of respect for Woz, but he's an engineer, not a salesman. Jobs was a PT Barnum, yes, but he knew what would sell (at this point the probably-apocryphal story comes to mind about Henry Ford saying "If I'd asked my customers what they wanted, I'd have ended up breeding a faster horse".)
A company like Apple needs a leader who's part businessman ("what will make money?"), part engineer ("what is possible?"), and part showman ("what will people desire?"). Woz isn't that mix, and Cook certainly isn't.
There's an SMBC web-comic from a few years ago that for me, kind of summarizes what an Apple led by Woz would be like: http://www.smbc-comics.com/comic/2012-05-01
