MIO Alpha watch goes on sale for $199, touts EKG-grade heart monitoring on the run

As popular as heart rate monitors can be for runners looking to improve their health, they're often definitions of compromise that require bulky gear or direct finger contact to reliably find the heartbeat. MIO's newly available Alpha watch may be just the remedy for those who aren't content to bulk up or slow down to avoid that guesswork.
