A new Band update went out this week. Android users with Cortana can now integrate the two with Band.

Also, a neat article that compares a lot of the fitness trackers out there.

One of the features I'll be using later today on the treadmill is Heart Rate Zones.

Anyway, just wanted to throw some new information out there for this thread. The Band gets updated about every 3 weeks with a new feature. I have a Google alert setting to email me on Fridays about anything Band related so I can stay apprised of the happenings on my wrist, be it a future feature or something that's just happened (I already knew about the Cortana integration since I've updated already).
