I had a Pebble Time Round, too, and it was great. For me the Pebble hit a sweet spot for a smart-enough watch that allowed me to keep my phone in my pocket. I could get notifications and reply to them right from the watch. I have a Withings SteelHR now, and it's great as a watch + activity tracker, but not being able to dictate replies to the notifications I get means I reach for my phone more now than I did with my Pebble
