Not too many crazy new idea areas to see this year, but still lots of interesting incrementally improving products.
Did badge registration at the airport for the first time. Loved it! It definitely saves time in the morning.
Uber and Lyft has made the whole chaotic convention center transportation aspect much more pleasant than it was in the past. Don't rent, drive and park, just Uber and Lyft around Vegas, you will save a lot of time.
I keep trying to do CES in 2 days, its not enough. Even if you truck around in Ludicrous mode it takes about 2.5 days.
