I use the phone feature on my iPhone maybe 1 time a week and that tends to be pretty short. My phone bill is consistently under 10 minutes for phone calls and less than 20 messages sent per month. I just don’t use my iPhone as a phone most of the time. It’s a computer with an internet connection in my pocket.
Now the way I see the Apple Watch (or WATCH?) is very much the same. It is and will be the computer with an internet connection on your wrist. Maybe this is not IT, but just like it took years for the iPhone to evolve, time (heh) will make this watch better.
