My two caveats are battery life and wrist straps. The early reviews suggest about 12 hrs battery life which is the bare minimum I'm willing to accept. I don't mind charging it every night for the increased functionality over my Pebble. The one disappointment is the lack of steel bands at launch. I'd prefer to get that now from Moto instead of paying extra when it's released later this fall. Despite those issues, I'm buying one today.
