Following the Macworld keynote on Tuesday The New York Times' David Pogue had the chance to talk to Apple's Phil Schiller.
Pogue naturally questioned Schiller on why the company had decided to pullout of Macworld in future years, Schiller pretty much restated Apple's press release saying that Apple stores "introduce more people to Apple’s products in a week than 100 Macworld Expos. Trade shows just aren’t worth the effort and the money."
Schiller also noted that Apple was under immense pressure to come up with a new revolutionary product every January. According to Schiller Apple sets itself to several key product cycles:
the holiday season (Novemberish), the educational buying season (late summer), the iPod product cycle (October), the iLife development cycle (usually March), the iPhone cycle (June). January doesn’t fit ANY of them.
