Been here 3 years in a row and it starts to feel the same to me now, but it's definitely interesting and there is a lot of stuff to take in. It takes me about 2 hours for each South, Central, and maybe North hall too, but I go fast and I only stop at the stuff I care about. Otherwise you should be ready to spend days here and walk for miles. Yes, I'll get a curved phone and maybe a curved TV (I'll read this post in a year or to and laugh probably), and also some wifi enabled LED bulbs (those are here to stay). It's fun to try so many gadgets and talk to so many people, get here if you can - it's for industry affiliates only.
