The true test of Steve's legacy will be whether Apple can continue in the image he molded for it well beyond his departure. Great CEO's are felt for a long time after they leave.
That's a nice sentiment, but I think Steve Jobs has already done more than enough to establish himself as the Greatest Business Leader of All Time. No hyperbole, I mean that quite literally and seriously.
It will have to change. There's a certain amount of "Steveness" that just can't be learned or absorbed.
I expect Apple's aggressiveness, not to lessen, but to even out a bit.
