I'm also not sure if they did the marketing right. All the clips from the sci-fi movies and shows pulls you in at first, but for me to buy something like this I need to be sold that it's critical to being as efficient as possible. The marketing I've seen makes me feel like I need to buy it to fulfill a childhood fantasy, which isn't enough to make me buy it.
Plus I've heard it's a bluetooth watch that only works with the Samsung phone. That narrows the market pretty thin. Rumor has it, Apple is working on a watch too.
