Need help with a "lifestyle" band

I want a Jawbone Up/Nike Fuel Band sorta device but I totally torn on what to get. I really want it to keep track of my running I don't know if these would do as good of a job as just a straight up GPS watch.

Anyone own these any of these devices? Also what do you primarily use it for?

Sorry if this is the wrong forum but I didn't really know where to post it.
