As far as "nothing wow" - that's called being jaded due to constant exposure to information on the internet. I've worked my trade shows than I can remember, MacWorld, CES, Digital Design something or others large and small, and even a large Grocery Innovations show. Once you've done a couple, everything else is the same. Even at CES there's really nothing that really makes me go "wow" when I read about it online, and the last one I worked was in 2005. But this has to be taken in perspective, as I'm primarily in IT, I am constantly exposed to every bit of news throughout the year - there's really nothing over the course of one week in January that's going knock me over. That said, I can appreciate that there are plenty of cool and noteworthy things on display at any trade show - I just might have already known about them 6 months prior.
Not too many things in general make me go "wow" anymore, but this year's SDCC had a lot of cool stuff on display - more than you can shake a stick at.
