In addition to the keynote by Marc Benioff and Industry Visionaries such as Guy Kawasaki in the morning, you will be able to attend 1 of the 3 tracks as well as get hands-on at the Apex Code lab session in the afternoon.
The Apex code Lab will be open from 11:30am – 5am. This will really give you the opportunity to get hands-on the Apex Platform and Apex Code with the help of key engineers from salesforce.com. At the same time, the 3 tracks will allow you to learn and watch demos on Apex Platform, Enterprise Mashups or even how you can start your own On-Demand startup.
