I've always worn a watch and still do. The aWatch does not attract me in the least. Not in function. Not in style.
I am not surgically attached to my phone. (annoys me that my iPhone 4 doesn't have notification LEDs) I don't want my watch to be dependent on another piece of equipment to be functional.
Charging devices is a necessary evil, it is one way in a sense that makes us slaves to our devices.
I don't want to have to charge my watch nightly. Miss a night, no watch the next day. Travel, yet another charger to bring.
But then again, My lifestyle is a collection of anachronisms.
I am more likely to consider the aGlass then the aWatch.
