How Jawbone UP Works

Author's Note

The Jawbone UP is an intriguing device. It's extremely portable. It's water resistant -- you can even wear it in the shower. There's no real reason to take it off other than to charge it or synchronize your data. That might give the UP an advantage over other devices that are easier to misplace. But if you don't own an iOS device, the UP is just a fashion accessory. As someone who has tried a few different gadgets designed to keep me active and in shape, I'm curious to see if the UP can hack it in the long run.
