Fitbit has a lot riding on its new smartwatch line

Fitbit needs a hit this upcoming holiday season from its newly-released Ionic smartwatch line. The company scored big with its fitness trackers but sales have lately suffered from competition, both from more elaborate alternatives from Apple and cheaper models from Asian manufacturers. Fitbit has packed a lot into Ionic. The $300 wearable can run third-party apps, make mobile payments and do health monitoring.
