My wife often says I'm fat, but that's hardly a motivation for me to resume my exercise routine. Then the ASUS VivoWatch landed on my desk, so I had no choice but to get back on the treadmill for your amusement. To keep things short, it turns out that this fitness-centric smartwatch does have a couple of compelling features that made me interested in getting fit again -- more so than the other basic (as in no heart rate monitoring) fitness trackers that I've long left in the drawer. Also, the VivoWatch can pair with both iOS plus Android, and costs just under $150 in Taiwan, meaning it'll be going head to head with the similarly priced Fitbit Charge HR around the world. So is ASUS' first fitness device worth trying? Or should you stick to some more mature offerings? Let's take a look.
