At the end of October in 2014, Microsoft surprisingly released a late night press release about a new device they were launching. It was the Microsoft Band, which is a fitness wearable that was a key component of their Microsoft Health service. It was their first real wearable, and it was packed with sensors to track everything from your heart rate to your sleep quality. At the Microsoft devices event in NYC on October 6th, Microsoft announced an updated version of the Band, known as Band 2. Its goal is to provide even more health insights, while being more comfortable and stylish than the original Band.
