I’ve had most of the week to wear the $129 Jawbone UP and I thought I’d offer a few impressions for those unsure which model pedometer to buy. I’m a Fitbit man myself because I’ve gotten used to moving the minuscule dongle from pocket to pocket and I have only lost one in my travels. But - and this is a big but - I could be convinced to move over to Jawbone if they fixed a few niggling problems.
