I think Peter Ha from Crunchgear has probably honed in on the most important thing to be taken-away from Steve Jobs' announcement that he will be stepping away from Apple as CEO for at least six months:
As mercenary as it may sound, now that Steve’s out of the picture (even if just temporarily), we can all stop wondering what Apple will be like with Steve out of the picture. Just the threat of a Steve-less Apple was enough to cause conniptions in some people. Now we can move past the vague fears and deal with reality.
A reality which is: Steve Jobs is not the sole genius, creative force or driven narcissist at Apple. They'll continue to do fine.
