Steve Jobs is having to step down as CEO of Apple (while remaining chairman) due to failing health. The poor guy has gone through so much ill heath in recent years that I feel that it is a little unfair that he has had a relapse or come down with something else.
However the markets seem to hate the news. They probably remember when he last wasn't in day to day charge of new developments and Apple nearly went belly up.
If this event stops the insufferable smugness of the Apple 'Fanbois' then I will be forever grateful.
