Fitbit's Versa smartwatch is available for pre-order and offers an interesting alternative to the market-dominating Apple Watch. For a start, there is the price: The Fitbit Versa costs US$199.95 and the Apple Watch Series 3 has prices starting at US$329 (from the Apple Store). Fitbit claims the Versa has a battery life of over four days, which certainly beats out the 18 hours that Apple advertises for their Series 3 (GPS) wearable.
