you forgot the person you will do a handstand and occasionally clap while jumping up and down, making the watch turn on all the time. The arguments are getting better. It takes a bit more for the screen to light up (you have to raise your arm and look at it) and you make it sound as if this was happening all the time. I sat through a handful of movies with my watch on and I typically watch the screen rather than my watch.
Come on people, you are making up weird scenarios to justify this feature - the only good point so far was from the guy who wears the watch when sleeping.
Actually I simply fold my arms and the screen on the watch turns on. Then if my arms are over the watch it ends up changing the watch screen.
I'm not saying this is the biggest thing ever but it's much easier than you seem to make out to turn the screen on.
