I read AP (Associated Press) article calls Steve Jobs master inventor, http://www.foxnews.com/scitech/2011/08/24/steve-jobs-at-apple-master-inventor-marketer/ here is a list of his patents, http://www.nytimes.com/interactive/2011/08/24/technology/steve-jobs-patents.html#patent/voicemail-manager-for-portable-multifunction-device_7996792 All his patents are about packaging, user interface of computer or device, I would not call him master inventor, that title should go to inventors like Tesla, http://www.teslasociety.com/biography.htm what is the difference between AP and People magazine? :)
