- Product showcase. Cases, speakers, software. More products focused on iPhone/iPad than Mac. eWeek slideshow has a good overview
- Breakout sessions. The MacIT breakout sessions (where I spent most of my time) focused on enterprise deployments. However, I attended some excellent MacWorld/iWorld sessions as well on a wide-range of topics from subject-matter experts
- Networking. Plenty of receptions both at the Moscone Center West and at nearby hotels to speak with other attendees.
