If i said that I wasn't happy WinHEC is over i'd be lying. But not by much - I had a very good time this year. I had a number of very interesting discussions with people - about how to use UMDF for their projects, about general kernel-mode programming questions, and even a few enjoyable ones around DMA :)
Meeting everyone, having good conversations and getting to peddle the work that we're doing is the fun of WinHEC for us Microsoft people. So for those of you who were there, thank you for that.
