Woz has also been out of the picture in Apple since before the Mac. He's been an outsider for close to 30 years, and has publicly stated that he was not close to Jobs.
It's not clear that his involvement means much in terms of making it an accurate portrayal.
Yeah...but Woz was very close to Jobs pre-Macintosh. Considering Apple's early years consisted mostly of Woz, Jobs, and Mike Markkula, I think Woz would be essentially to understanding the early part of Jobs' success, without which the post-Macintosh days would've never happened.
