Me too. The 6 is a wonderful phone, but as a runner, it just seems a little too big to carry. My current 4s is a good size, but way too heavy. (I wish I had never gone to the Apple store and handled the 5s. So light compared to the 4s.) I think I'm right, in that, the AppleWatch for running, GPS, etc., needs for me to carry the iPhone as well. If that's the case, I'll forgo GPS and carrying the iPhone and just concentrate on HR while only wearing the watch. Oh well. Best.
