While riding Caltrain from MtView to San Francisco last Thursday (4/2) I noticed someone below wearing a small (38mm) Apple Watch. I snapped a few photos ( https://twitter.com/helmstetler/status/584966770978459648). I asked the guy once in SF if he like the watch. He said it was, "really great". He then covered the watch with his sweater (placed over wrist, not worn) and began to walk away quickly. He used the watch a few times to I beleive read text messages and look at other notifications. He seemed more interested in playing a game on his iPhone vs using the watch.
