The Alta arrived today and I'm liking it so far. The bigger display is nice and it's about half as wide as the Charge is. We'll see how the battery life is.
Surprisingly my Charge worked all the way through my vacation but it's pretty much toast now. Ordered a Fitbit Alta today, we'll see how that goes. It has the features I need and the thinner profile will be nice I think.
The vivofit 3 looks pretty interesting as well, I really don't need any of the fancy stuff, just step, distance, calorie, etc tracking and the ability to manually enter data that it can't track.
