Wearable computing is here, as was evident at CES 2014. One of the most evident applications of this trend is health and fitness gear. There were a lot of bracelets on display, but I already wear a watch and don't want another thing on my wrist. The ibitz is a handy and compact fitness tracker that clips to your belt or clothing and you can forget about it. And thanks to Bluetooth 4.0 Low Energy, it can last for months without recharging.
