If the AVP is a failure (maybe too soon to tell), Cook was CEO at the time, and the buck stops with him.
Holding Jobs responsible for the Lisa failure, a couple of years after he'd been kicked off the project, at a time when he wasn't CEO, is hardly the "same standards".
(Since he then took over the Macintosh project and pivoted it from being the Apple IV to an affordable appliance-ified mini-Lisa kinda suggests that he was right and the people who chucked him off Lisa were wrong).
I think a lot of people are mis-remembering Jobs as being CEO of Apple pre-1985. More of a loose-cannon "founder" often at loggerheads with, and at the mercy of, the board.
Then, when Jobs did come back as CEO his first task was to stop the company going bankrupt & fix a legendarily awful product lineup. I don't think anything that Cook has done is comparable to the transition from unpopular and outdated Performas of 1998 to the iPhone-driven Apple brand of 2011. Cook has done wonders to build the company financially, but that wouldn't have happened without the solid base he inherited.
I'm certainly not writing off AVP yet. The comparison with the Lisa could turn out to be apt - except the practical, more affordable "Mac" to the AVP's "Lisa" is now overdue... Or it could be more like the Newton (not Jobs' fault) and we'll have to wait 10 years for technology to catch up with its aspirations and for the corresponding "iPhone" product to come along... AVP will be great once it can be made the size and weight of a pair of safety glasses with all-day battery life. Not sure that's gonna happen soon.
