I'm still not entirely clear what the Apple Watch is supposed to do for me, especially when it's still reliant on a cell phone to function.
It does have a GREAT use. I see everyday people using their cell phones in their cars while driving, phone on the ear. All new and luxury cars even. Im sure those cars have bluetooth, but somehow people dont know how to use or dont like how it sounds or whatever.
Since Apple watch allows to talk through it, Im sure it will diminished the chance of accident for those who drive with the phone on the ear. Since talking to the wrist allows the hand to grab the wheel, while if fit is holding a phone it is more difficult.
I know that Apple wont be able to promote it this way, but I really believe that iphone users will have fewer accidents of they use an Apple Watch.
