The San Francisco show went on January 5–9, 2009. On December 16, 2008, Apple announced that the 2009 conference will be the last in which the company would participate. The conference's keynote address was delivered by Apple's Senior Vice President of Product Marketing Philip Schiller, not Steve Jobs, as has been the custom for the past ten years. Steve Jobs issued a press release stating that the reasons for his absence were health-related, specifically citing a hormone imbalance.
At Macworld 2009, Apple announced the release of iLife '09, iWork '09, and the new 17-inch unibody MacBook Pro with built-in battery. Also, Apple announced that iTunes would begin to sell all music DRM-free, with a three tier pricing system per track: $0.69, $0.99, and $1.29 (or £0.59, £0.79, and £0.99 in the UK). This differs from Apple's previous model with only one price per track of $0.99 (£0.79 in the UK). Apple also announced that tracks can now be downloaded over cellular networks on the iPhone.
