Apple announced today that this year would be Apple's last year participating in Macworld Expo and that Phil Schiller, not Steve Jobs, would deliver the final keynote address. Understandably, speculation has been directed towards health concerns about Steve Jobs as the reason for the withdrawal. Jobs underwent surgery for pancreatic cancer but has been said to been cancer free as recently as July. CNBC reports that Steve Jobs' decision was one motivated "more by politics than his pancreas". Instead, the author believes that Apple has been trying to separate itself from Macworld for years with the use of "special events" to introduce new products a few times a year. This is said to give Apple complete control over its own message. Meanwhile, Macworld Expo organizer IDG is putting on a strong face saying that they are committed to Macworld 2010 and "look forward to many successful years of Macworld to come."
