Normally I don't do "I agree" comments but given how downvoted the parent comment is (-4 at the time of me writing this), I am going to make an exception.
Disregarding the technicalities (Mr. Jobs owns only a small part of Apple's shares) the parent has a point in that if you're happy with what you're doing, no, if you love what you're doing and have financial stability already so that you don't need to worry about money, ceteris paribus, you might not want to sell your business. It might not make you any happier or your life any more meaningful. Of course, if you feel like doing something new, then it makes sense.
Not exactly - if we're going to have a counter-example, we should have a valid one (e.g. a privately owned company, since it's self-evident that every public company does have its sale price).
I used to agree with you, but ever since Jobs' battle to stay alive and still not handing the reins over to someone else and enjoy the rest of his days spending his dough I find myself agreeing with the GP, it is very well possible that Apple is the thing that Jobs enjoys doing the most in the world, and that he really wouldn't give up his role there and his stock in return for any amount of money.
Those that have stood with one leg in the grave are usually pretty aware of the time they spend and how they spend it, I don't see Jobs letting up at all.
I'd guess a merger that gave him a chance to bury Microsoft might make him sit up and take notice. HP maybe? Their hardware and channels exclusively running Macos would be a juggernaut.
Steve Jobs has already thrown away large fortunes by simply not exercising options he was granted. He apparently has a lifestyle he's happy with. So more pedantic way to say it is: anyone who isn't doing exactly what they want to be doing and living the level of lifestyle they want to be living has a price.
