Yeah, just reading the many books on the early days of Apple tells you that. I mean who else would be able to yell at a another CEO in his office like Jobs did to Gates?
Not many. Jobs is a unique, control freak, likable CEO. Just going by who is working at Apple these days, Apple has a bright future if these people stay around and don't get lured to another company(and with how the tech indrusty is, not very likely as when the boom happen...Unless Google wants a taste).
And if anything the Board of Appel has many good candidates for replacement, such as Al Gore.
