After Nokia buy, Withings debuts e-ink fitness, sleep tracker

Smartphone maker Nokia did a deal to snap up French digital health company Withings late last month for $191 million. Now, the Paris-based Withings has rolled out a new activity tracker, Withings Go, that's inexpensive and works in water. The device retails for $79.95. It features an "e-ink" display to show data on walking, running, swimming and sleep; these are typically confined to more pricey trackers. The display is always visible, even in the water. And it has a battery life of up to 8 months without recharging. More
