I agree with mechou and HeroOfPellinor the presentations were like infomercials, they delivered a loaded marketing speel to us. The first half seemed too drawn out (it didn't help to be in small uncomfortable chairs, outside in the heat, in the bug infested lawn).
The "buffet" wasn't too great, but for free, anything is okay!
The second half was more of the same, with a media center demo, and minor cpu swapping to show performance on stage, the Q&A was a welcoming change from the "infomercial" presentations. They ended with some give-aways. As mentioned above, the other sposors together outdid what AMD gave away. Sad considering it was on AMD's HQ site.
Overall it was worth it if you got the bundles.
