I totally agree with this ^. The key to wearables is to make them fashionable - to make them into something a lot of people want to wear, and want others to see them wearing.

Wearable devices are still very much on the fringe - mainly due to lack of style - and style is very individual. This watch, regardless of its somewhat indistinct purpose, will be able to appeal, on beauty alone, to a vastly larger group of people than it otherwise would if it were "the one."
