IMHO, John Sculley was by far the best CEO Apple as ever had, he did what no one before or since him has ever been brave enough to do which is to tackle the question of growing market share head on, he allowed cloning etc.. which in hindsight was the wrong decision but we had to find this out and at least he had the balls to do it along with the balls to get rid of Jobs who was a loose cannon taking Apple swiftly down the pan.
The time that he was the boss also saw Apple's most innovative period without question. We got the Newton a product years ahead of it's time, we at last got a cheap affordable color Macintosh in the shape of the LC before that you had the $5000 Macintosh IIfx and we also got a massive jump in performance with the Quadra, in this time we got AppleScript he gave us System 7 which in reality was with us until this year in the guise of OS9 it goes on...
Yeah, Steve Jobs has charisma by the bucket full but in reality he is nothing more than an egotistical parasite sucking Apple dry, look at his drawings from Apple this year, $1 salary my arse!! he's had over $200,000,000.00 out of Apple in the last 12 months. He didn't give Apple OSX he sold it to Apple for over half a Billion dollars and it's taken another four years to get it to the stage where it's a usable system and all at Apple's expense. We've sat and watched Apple's lead in processing power dwindle away while he's been in charge and only now have we got the G5, a chip that let's us draw level with Intel based systems again I could go on..
The thing is that Apple isn't about CEO's the unsung heros at Apple are the men and women behind the scenes who dream up and create the products and us the loyal users.
