I've worn several "wearable" devices - the Jawbone UP (more than a year) and a Basis watch (4 weeks). Surprisingly to me I found that my life - as sedentary as it is - didn't play well with expensive, breakable, things on my wrist. I've just gotten used to not having something there. My children ripped it off, I smacked it on door frames, accidentally showered with it, and scratch/banged them pretty badly when doing random car work or goofing off in the backyard. While the wearables were expensive, they aren't nearly as expensive as my phone, which does hold up much better. I'm pretty wary of the idea of putting that on my wrist now.
