The guest on this week's nationally syndicated Motley Fool Money radio show is Adam Lashinsky, editor-at-large of Fortune magazine and author of Inside Apple: How America's Most Admired -- and Secretive -- Company Really Works. In this audio segment, Lashinsky discusses CEO Tim Cook's strengths and weaknesses and the ways in which he freed Steve Jobs up to focus on Jobs' own areas of interest at the company. Lashinsky also analyzes some of the other key executives at Apple, including Jonathan Ive (design) and Scott Forstall (software), and states why one in particular would be the hardest for Apple to replace.
