The event takes place between January 9-13, 2006 at San Francisco's Moscone Center. Attendees who register online before December 9, 2005 at can do so at a discount.

This year's show introduces a new conference "feature", Market Symposiums. These day long conference events focus on specific markets to help users get the most out of their Macs. Currently planned symposiums include: Small Business, Education (K-12), Podcasting, Art Directors, and New Media Artists.

The event's opening will feature a keynote speech (on January 9 at 9am), which is traditionally delivered by Apple CEO Steve Jobs. However, this year's speaker hasn't yet been named.
