Over the past few years, the Steve Jobs keynote at Macworld has been one of the biggest events for all things Apple.  For Apple followers and enthusiasts, the keynote has set the direction and focus of the Apple community for the rest of the year.  The Macworld event has expanded in recent years and the 2007 event will be the largest in history. 

The 2007 keynote will be a huge event as people, press, and companies around the world will be eager to hear how Steve Jobs will set the tone for Apple in 2007.  Many will be anticipating the announcement of iLife and iWork updates, presumed to be called iLife '07 and iWork '07.  Many are eagerly waiting for the final details, specifications, features, and name of "iTV", Apple's recently previewed set top box.  Apple is also likely to provide additional information and features of their next version of the Mac operating system, Mac OS X Leopard 10.5.

The 2006 Keynote saw Steve Jobs announce software updates iLife '06, iWork '06, and Mac OS X 10.4.4.  The event also saw the introduction of the first Intel based Macs, the iMac and MacBook Pro a full six months ahead of schedule.
