Stop by the Microsoft "Ask the Experts" area and ask me some technical questions about Windows Server 2008. I don't know if I will have anything to give out for prizes, except for nuggets of information.
Just keep in mind, I'm not a sales guy. I'm more well versed in telling you about configuration scenarios for Hyper-V than what the licensing cost would be. I can also tell you the technical reasons for upgrading to Server 2008 and not standard marketing phrases of "Easier to manage" or "Reduced TCO". Those are all valid reasons but I'd rather tell you about the technical aspects, like SMB 2.0 and Read-only Domain Controllers.
I'll also be at the CDW/Berbee booth from time to time too, since we are one of the partners at the event.
