Jaybird's Reign fitness wearable promises to tell you when you want to work out

Because there might not be enough fitness wearables, Jaybird has announced its own wristband -- Reign. Health-centered (just like the company's recent Bluetooth headphones), we're promised activity and sleep monitoring, separating out users' movements by specific physical activity and sport. Details are otherwise pretty scant at this point: It will work with iOS, but we're waiting to confirm Android compatibility and we're looking to hear more details about "Go-zone," which will apparently read when your body "wants" to exercise and then remind you to do so. We've still got a lot of questions left to answer, but we'll be hunting down the band at CES for the rest of the answers.
