On the bandwagon
This is the Microsoft Band. Only available in the USA right now but the first product by Microsoft to get into the watch/wearables market.
One of the interesting things about this wearable is that it is not just for Microsoft products. Unlike the Google Wear and the Apple Watch this product is open enough to work with IOS, Android and Windowsphone.
Right now it is only available in the USA at a relatively cheap $199. Cheap by comparison with Google and Apple wearables.
Since I am not exactly a fitness and sport person this will pass me by pretty quickly. However I do think this is another Microsoft product reflecting a focus on mobile and working across devices.
