While we can think of things as "Be the next CEO", here is something that we think you will find more useful:
1. Education: Learn about new technologies and prepare for a brighter future
2. Win scores of goodies at the event
3. Network: With other professionals in the area (and did he tell you that he is looking for co-founders for his new setup)
4. Food & snacks served
5. Get your real world problems solved
6. Get the download of speaker decks and code snippets/ scripts
7. COUPON: Continue learning at Hands on Labs (at a later date)
