According to Forbes Microsoft will launch a wearable device in a few weeks' time-- specifically a cross-platform smartwatch with passive heart tracking and a battery life of over 2 days of regular use.
Confirming the Forbes report is news site The Verge.
Rumours of Microsoft working on a smartwatch date as far back as April 2013, when the Wall Street Journal reported on the company working on "designs for a touch-enabled watch device." More recently a Forbes story from May 2014 tells of a Microsoft wearable featuring "optical engineering expertise from Microsoft's Xbox Kinect division" and a long-lasting battery life.
If the Forbes story is true it means Microsoft might emerge as a dark horse in the race for smartwatch dominance-- after all, battery life is one main complaint faced by the current crop of smartwatches, as the Samsung Gear, Moto 360 and even the Apple Watch demand daily charging.
