I don't think it's fair to attribute all of the recent Apple products to Cook. Most of those products, if not all, were probably well into the design and/or testing phase by the time Cook took over. In another 12-18 months, I think we can then start analyzing products to find Cook's DNA in them. At minimum, I'd say that the 2014 iPhone, iPad and Mac lines will be a much more accurate representation of Cook's product leadership.
