Sure, Jobs doesn't hand-build every Mac and write every piece of software (in fact, he doesn't write anything and never builds anything). But what Jobs really does is approve every single decision that Apple makes. The new product designs, new product IDEAS, and so on.
And to everyone complaining about the premium cost of the Macs, you get what you pay for. In this case, you get a seamlessly-integrated, very stable, aesthetically pleasing computer with a damn cool OS. Nothing's stopping you from buying a $299 bargain-bin desktop from WalMart and slapping OS X on it... except the lack of drivers, god-awful instability, reduced usability of some applications and lack of official tech support.
Want cheap? Buy a Dell.
Want good? You're in the right place.
