It is a much larger show this year and somewhat scattered. One looses too much time shuffling between locations. If you spend any time talking with the factory people, you'll likely run short. North Hall is the least interesting for me because it is mostly cars and autosound. But if you want to see the electric cars, North is the place. There is an explosion of Aisian companies (many displaying palm sized Bluetooth speakers), less e-cigarettes. Lots of battery and charger options, 3D printers, drones, robots, health monitoring bracelets, and "smart" outlets. There are also a ton of uninteresting "home automation" schemes that don't seem to integrate with anything useful. They seem to be vehicle to justify monthly fees. Of course. BadDog tools is there.
