I've been using my Jawbone UP for several weeks now: http://v1s.it/1atmW1k It's really awesome! I can shower in it and everything!
The best part is that I wear it on my wrist, like a watch.
Before the UP, I had the Fitbit Zip and the Bodymedia armband, but they were a hassle for me.
The Fibit Zip I had to remember to clip to my clothes.
The BodyMedia device I had to wear around my forearm.
With both, I'd forget to put them on, or they just felt like they were in the way.
I tried to get the Fitbit version that you wear on your wrist, but it was on backorder forever, so I canceled that order and went with the UP.
I have no complaints about making a different choice. 😀
