This week is turning into a notable one for wearable devices thanks to a couple of announcements out of Asia. First, Xiaomi announced plans for a device that will retail for just $13, a truly new low pricepoint for the genre, and now Razer is revealing that its upcoming new product will integrate messaging app WeChat. The Nabu smartband borrows some functionality from a smartwatch, alongside the standard fitness and health tracking capabilities that we expect. But integrating WeChat is a very interesting move, particularly in China where the service is ubiquitously used and is even becoming a platform for developers who seek to super-charge their apps. Razer tells Re/Code that Nabu will debut in China before the end of the year, but will make it over to the US — and, we presume, other international markets — within the next couple of months.
