Back at the Apple Worldwide Developer Conference in San Franscisco, Jobs looked very skinny and frail. Thus creating speculation among many people that maybe once again he might have cancer. This caused Apple’s Stock Ticker Symbol (AAPL) to drop around 8 percent on that day. Now news is coming around that at this year’s MacWorld Conference, Steve Jobs will not be delivering the keynote; instead, Phil Schiller will take over. Schiller is currently Apple’s senior vice president of Worldwide Product Marketing. Also, this will be the last MacWorld conference for Apple. AAPL is currently at $90.00; we’ll see how much lower it will dip in the following weeks as more details emerge.
