There are three broad categories of watch people these days:
Consider a fourth category, though likely not as broad as what you have already listed. That would be athletes and fitness buffs who obsess over the statistics of our training activities. We regularly wear huge GPS enabled watches that track our activities and statistics. The more popular brands include Garmin devices and if you have ever had the "pleasure" of using anything designed by Garmin's UI team you can imagine how excited some of us are to have an alternative. A cell phone with a watch peripheral would be a great combo. In my particular case, I perspire heavily when I run so I have to carry my cell phone in a zip lock bag, making it awkward to get to. Having a display on my wrist would be a significant usability factor. At ~$200US the watches are priced competitively with the stand alone units.
The only reason I have not ordered one is that I'm waiting to see how the Moto 360 stacks up against these two.
