Just last week, Google trotted out Android Wear, its first big push to extend the dominant smartphone OS to wearable devices. The first Android Wear device, an LG smartwatch, was also announced and more are sure to come. They’ll add to scores of wearables that have been unveiled this year, starting at International CES in January.
The devices purport to improve lives—even to help save them—but not everyone is rushing to buy them. In this untested market, the many unanswered questions include concerns about user privacy and what form-factors will be comfortable and attractive enough for long-term use.
