Is Apple's biggest problem in delivery?

I agree with this MacLife article 100%. Where Apple is really missing Steve is on the presentation front. Steve was an incredible salesman. Tim Cook and Phil Schiller don't even come close to what Steve could do on stage. Of course Apple can't replicate what Steve did but I think they need to find someone better to do their product intros.
